(Update 2020) When genealogists take an ancestry DNA test, they are looking for more than just their ethnicity results. They are also very interested in receiving information on other people who have tested who closely genetically match them. They want to know who the closest matches are, and if those matches have family tree information that they can share.
However, with all the people testing these days, (some being genealogists and some not) the volume of matches can become overwhelming very quickly.
Are you one of those people who have way too many genetic “4th cousins or closer” among your DNA matches? Have you ever wondered “What do I do with all these matches?!” If so, keep reading. We’re going to explore some of your options, and most importantly, how to determine how genetically close your cousins really are.
Doing the DNA Math on Your Cousins
Math can provide us with a degree of certainty in genetic genealogy. Each of us has two biological parents. We have four biological grandparents, and eight great-grandparents.
However, the farther back we go the less we can rely on math.
For example, on paper you should have sixty-four 3rd great grandparents. However, many of us find that the same person occupies more than one slot on our pedigree chart. While this significantly decreases the workload for traditional genealogy, it adversely impacts your genetic genealogy. Especially when it comes to that long long list of 4th cousins you have in your match list at any of the three major DNA testing companies.
Depending on how intermarried your lines are, you may be seeing individuals on your match list that genetically look like your fourth cousins, but they are genealogically your sixth cousins – EIGHT TIMES! So how can you tell the difference?
There are two parts to that answer: one you can control, and the other you can’t.
Distinguishing DNA Matches with Genetic Tools
While your fourth cousins and your eight-time-sixth cousins may look similar genetically, there are often small clues in the genetics that can help you tell the difference. This distinction can sometimes be detected by a testing company who, through research and validation, has been able to fine-tune their algorithms to detect these subtle differences.
Your Genetic 4th Cousins
You can participate in this double checking process by using some of the genetic tools that are available to you at Family Tree DNA, or at Gedmatch.com. But since you may not be an aspiring geneticist, let’s focus on the genealogical work you can do to determine if a match is truly a fourth cousin.
Use Google Earth to Plot Your DNA Matches
A fourth cousin designation just means that you and your match are separated by between six and twelve degrees (people). So that might be five back on your chart to your common ancestor, and five down to your match, which would make you true fourth cousins. It could also be some other permutation of that.
For our example, let’s assume true fourth cousins. That means that the two of you share one of thirty-two 3rd great grandparents (16 couples). In order to find out which set, you have two genealogical identifiers: surname and location.
Therefore, the first thing you should do is make a list of the surnames and locations of those thirty-two 3X great grandparents.
Now, most of us do not know all 16 of those couples, so you are going to have some holes. Feel free to fill in those holes with surnames on subsequent generations that will carry through to this fifth generation.
A great tool to plot your own list of ancestors geographically is the free downloadable Google Earth software.
Check to see if you have the latest version of Google Earth downloaded to your desktop or laptop computer. On your desktop, look for a grey and white globe. If you see a blue and white globe, you have the older original free version of Google Earth. However, a few years ago, Google made their Google Earth Pro version free to everyone, and it is now the standard.
If you do have Google Earth Pro (the grey globe software) then you’re ready to go.
The grey Google Earth globe on the desktop.
If you don’t have it, then you will need to download it.
If you agree to them, click the Agree and Download button
Follow the installation guide
When complete click Run Google Earth
Now that you have Google Earth, you can begin by creating a folder in the Places panel in Google Earth devoted to your 16 couples. Here’s how:
1. In the Places panel, right-click on MyPlaces and select Add > Folder:
Right-click on MyPlaces > Add > Folder
2. Name the folder and then click OK:
Creating a folder in Google Earth
3. Now you will see your new DNA folder for your 16 couples in the Places panel. If you don’t see it, look toward the bottom of the list. You can move the folder to any location within the list by dragging and dropping it.
Create a folder in Google Earth for DNA 16 couples
Once you have your DNA folder created fro your 16 couples, you can then easily plot your surnames and locations.
How to Plot Your Surnames and Locations in Google Earth:
1. Click your new DNA folder to select it. This will ensure that the placemark you are about to create will be stored in that folder.
2. In the search box (upper left corner of the Google Earth software) type in the first location and click Search. Google Earth will fly to that location on the map.
Type the locaton in the Search box and click Search.
3. In the toolbar along the top of the screen, click the placemark button to place a pushpin in that location:
Click the Placemark button in the Google Earth toolbar.
4. In the Placemark dialogue box, enter a title for hte pushpin placemark. Click the OK button to close the box and set your placemark.
5. Repeat the process for all the locations.
Then evaluate the fifth generation of your fourth cousin matches for genealogical information that lines up with any of the items on your list.
You can also plot the surnames and locations of your matches in Google Earth. This is where Google Earth really comes in handy. The free software makes it very easy to see when your ancestral home may be bordering the locations of your matches. Those with whom you find a similarity become your best matches, and your best chance of determining your connection. Those without an obvious connection cycle to the bottom of your pile for a genetic evaluation. You can perform these same kinds of searches for your second and third cousins as well.
As you begin to become more familiar with the fifth generations of your matches, you may also start to see patterns of surnames or locations emerge among your matches. These then become the surnames and locations that might be able to fill the missing spaces in your pedigree chart.

Findmypast announces the new catholic church records in their Catholic Heritage Archive this week. This new partnership with British and American Archdioceses will be a monumental help to those searching their early Catholic roots. Also this week, records from Italy and the Netherlands at FamilySearch.

Catholic Church Records in the Catholic Heritage Archive
Findmypast announced their new Catholic Heritage Archive this past week. They are releasing over 3 million exclusive records including sacramental registers for the Archdiocese of Philadelphia from 1757 to 1916 as well as for the British Archdioceses of Westminster and Birmingham from 1657 forward. This builds on last year’s publication of more than 10 million Irish Catholic parish registers.
The Catholic Church holds some of the oldest and best preserved genealogical records and in the past, have been difficult to access.
In collaboration with various Archdioceses of the Catholic Church, Findmypast is helping to bring these records online in one unified collection for the first time ever. Exclusively available on Findmypast, images of original documents will be completely free to view in many cases. Fully searchable transcripts will also be included, providing family historians from the around the world with easy access to these once closely guarded records.
Click “Play Now” below to listen to Sunny Morton’s brief interview with Findmypast about the announcement: [display_podcast]
The next phase of the Catholic Heritage Archive will include records from the archdioceses of New York and Baltimore as well as additional records from Philadelphia. There are over 30 million records in just these three dioceses. The digitization of the whole archive is a monumental undertaking and, when complete, will contain hundreds of millions of records for the USA alone.
Catholic Heritage Archive Holdings for This Week:
United States – Pennsylvania – Philadelphia – Baptisms
The Philadelphia Roman Catholic Parish Baptisms at Findmypast are the first of these record releases from an agreement made with the Roman Catholic Church to digitize their records. These baptismal records will include a name, their parent’s names, and residence at the time of the event.
Additional information may include place of birth, sponsors, minister who performed the ceremony, and notice of marriage. Catholic priests were charged with noting all vital events of their parishioners. If, for instance, a parishioner married outside her home parish, the priest who performed the marriage would contact her priest to confirm she was baptized and to share the details of her marriage, hence the marriage notice in the baptism register.
United States – Pennsylvania – Philadelphia – Marriages
You can now view a transcript and an image of your ancestor’s marriage register from the Archdiocese of Philadelphia in this collection titled Philadelphia Roman Catholic Parish Marriages from Findmypast.
Information contained in these records include the couple’s names, marriage date and location, and you may find dates and locations of the couples’ baptisms.
All Philadelphia Roman Catholic Parish records are from the Archdiocese of Philadelphia, covering Bucks County, Chester County, Delaware County, Montgomery County, and Philadelphia County.
England – Westminster – Roman Catholic Census
Another Catholic records resource from Findmypast includes the Westminster Roman Catholic Census 1893. As well as the typical information you would expect from a census (occupation, address, birth year, etc.), notes detailing the local priest’s opinion on your ancestor’s faith and dedication to the church let you find out if your ancestor was a good or bad Catholic. Scandalous!
England – Birmingham & Westminster – Roman Catholic Church & Parish Records
Four separate collections, also in the Catholic Heritage Archive at Findmypast, include Roman Catholic baptismal, burial, marriage, and congregational records for locales in England. The records released this week are for the areas covering the Birmingham and Westminster archdioceses. The amount of information in each of these record sets will vary on the age of the record, legibility, and the amount of information recorded by the parish priest. You will find both a transcription and a digital image of the record.
Provided by the Historical Society of Pennsylvania, Findmypast brings you a large collection of vital records. The first is titled Historical Society of Pennsylvania, Births & Baptisms. These records include images from a variety of sources spanning years from the late 1600s to the mid 1900s.
It is important to note this may not be the only place to find births or baptisms—and there may be records included that are not births or baptisms in this material from the Historical Society of Pennsylvania.
The Historical Society of Pennsylvania, Deaths & Burials collection will include records that may contain the following information: decedent’s name, date of death and burial, parish and diocese, and could include additional information such as military service, age, and birth date.
The Historical Society of Pennsylvania, Marriages collection is also a helpful group of records and include marriage records ranging from the early 1600s to the late 1900s. You can view a transcript and the original image.
United States – Pennsylvania – Congregational Records
The Historical Society of Pennsylvania, Congregational Records is a unique collection that may give you insight into your ancestor and the church they attended. Not only will images include lists of past ministers, but you may find additional lists of those persons baptized and confirmed. Some of these records may also be used as a source to discover the names of your ancestor’s parents and spouses.
United States – Pennsylvania – WWII Records
Screenshot from Findmypast of the Historical Society of Pennsylvania, WWII Casualty Cards.
The Historical Society of Pennsylvania, Word War II Casualty Cards collection is a group of records created by the Army so if something happened to a local soldier, the newspaper wouldn’t have to scramble for information. These records are particularly relevant in light of the fire at the National Archives and Records Administration in the 1970s when most World War II personnel files were destroyed.
Netherlands – Miscellaneous Records
We have brought you many collections from Findmypast, which require a subscription. However, these next few collections are brought to you by FamilySearch and are free to access.
Netherlands, Archival Indexes, Miscellaneous Records collection has been updated this week at FamilySearch. These records include many record sources, such as civil registration, church records, emigration lists, military registers, and land and tax records. These records cover events like birth, marriage, death, burial, emigration and immigration, military enrollment, and more. These indexes were originally collected, combined and published by OpenArchives. For the entire index collection and more information visit www.openarch.nl.
Italy – Trapani, Civil Registration
FamilySearch brings you updates to the Italy, Trapani, Civil Registration (State Archive), 1906-1928 collection. This collection consists of civil registration of births, marriages, and deaths within the custody of the State Archive of Trapani. Availability of records is largely dependent on time period and locality. This collection of civil registrations records covers the years 1906-1928 and may also include:
Residency records
Marriage banns
Indexes
Marriage supplements
Miscellaneous records
Learn More about Institutional Records Research
From schools and orphanages to prisons, hospitals, asylums, workhouses, and more, there’s a good chance one or more of your ancestors might be found on record in one of the many types of institutions. In this Premium eLearning video, Institutional Records Research Methods, Lisa Louise Cooke presents methods for finding your ancestors in institutional records, from establishing a workflow and investigating clues found in the census and other records to resources and strategies for digging up the records. This 40-minute video includes a downloadable handout and is available right now to all Premium eLearning members. Click here to sign up!
Italian civil records at FamilySearch have been updated for five specific localities. Births, marriages, and deaths are just a few of things you will find in these collections. Also this week, Netherlands, Sweden, Australia, and Alaska.
Italy – Italian Civil Records
FamilySearch has added to their Italian genealogy records this week. Five specific locales in Italy have Civil Registration records online. Civil registrations include such things as births, marriages, and deaths. They can also include marriage banns and ten-year indexes. Of course, availability of records will depend on the time period and the location.
This collection may include the following records:
Marriage banns (pubblicazioni o notificazioni)
Residency records (cittadinanze)
Ten-year indexes (indici decennali)
Supplemental documents (allegati)
The second collection titled Italy, Mantova, Civil Registration (State Archive), 1496-1906 covers several centuries. Images for this collection had been mistakenly made available to the general public who registered at FamilySearch. However, because of the agreement signed 30 June 2011, the publication rights of images belongs to the Italian National Archives (DGA) who publishes them freely to all on their Portale degli antenati: http://www.antenati.san.beniculturali.it/. Though you can see a transcript of the civil record at FamilySearch, you will have to visit the Il Portale Antenati to see the digital images. Some fees may apply.
Again, these civil records for Mantova will include such things as birth, marriage, and death records and in some cases, marriage banns and 10-year indexes.
Italian birth record online at FamilySearch.
The third collection is titled Italy, Grosseto, Civil Registration (State Archive), 1851-1907. These records will again cover birth, marriages, and deaths in the Grosseto locale. These records, like the others, are written in Italian. In this case, you are able to view many of the digital images online at FamilySearch without having to use the Portale Antenati.
The fourth collection titled Italy, Rieti, Civil Registration (State Archive), 1840-1945 covers the years between 1840 and 1945 of this specific locale. The records held in this collection will largely be the same as the others, but there is something special that these Rieti records hold. They include Catholic parish registers of Poggio Fidoni (Frazione of Rieti) for the years 1768-1860.
Also at FamilySearch, records have been added to the Netherlands, Archival Indexes, Miscellaneous Records. These miscellaneous records include indexes that cover many record sources, such as civil registration, church records, emigration lists, military registers, and land and tax records. These records cover events like birth, marriage, death, burial, emigration and immigration, military enrollment, and more.
Sweden – Norrbotten Church Records
Sweden, Norrbotten Church Records, 1612-1923; index 1658-1860 is a recently updated collection at FamilySearch as well. Church records from the county of Norrbotten contains indexes to births, marriages, deaths and images to clerical surveys, registers of birth, marriage, death, move-in and move-out lists, confirmations, and church accounts. Notice that this collection has some index-only items and there are some other items that offer a digital image of the record. Covering such a lengthy period of time, records will vary given the time frame.
The records are handwritten in narrative style and may be difficult to research for beginners.
Australia – Marriages
This week at Findmypast, we bring your attention to Australian Capital Territory Marriages. Each record result contains a transcript of the original record. The information available will vary, but information typically includes:
First and last name
Marriage date
Spouse’s first and last name
Registration number
State
Further details can be found on the marriage certificate itself, which can be obtained online from the Office of Regulatory Services. Due to the sensitivity of the information found on marriage certificates, the marriage must have occurred more than 75 years ago to obtain a certificate.
Australia – Victoria – Wills & Probate
Wills and other probate records are a fantastic resource for genealogists. They often contain names of heirs and prove relationships. Findmypast has updated the collection titled Victoria Wills & Probate. In this collection of mostly indexed records, some search results will also include an image of the original probate documents. Records cover the years 1841 to 1989 and may include the following information:
First and last name
Sex
Occupation
Residence
Death date
Grant date
File number
Australia – Victoria – Divorce Records
The Victoria Divorce Cause Books 1861-1938 collection at Findmypast may offer you answers to the reason your ancestors parted ways. In Victoria, the Public Records Office Victoria (PROV) holds divorce case records up to 1940. If you are interested in more recent divorce cases, you will need to contact the Supreme Court of Victoria. It’s important to also know that up until 1975, divorce cases in Victoria were heard by the Supreme Court.
These records will likely provide you with the first and last names of couples, petition date, who filed for divorce, and a case file number.
United States – Alaska – Vital Records
Did you know that this year is the 150th anniversary of the Alaskan Purchase? We have some great tips for Alaskan genealogy research coming up here on the blog in the next couple of weeks. In the meantime, get started on researching your Alaska ancestors with the FamilySearch collection titled Alaska, Vital Records, 1816-1959.
In these records, images of birth, marriage, death, and divorce records are available for searching. Though the collection is a bit on the small side, new records will be added as they become available. Digital images of births cover the years of 1816 to 1912, marriages for the years of 1816 to 1959, and deaths between 1816 and 1959.

Are your DNA ethnicity results exciting, confusing, inconsistent, exasperating…or all of the above?
Recently Kate expressed on the Genealogy Gems Facebook page her frustration with her ethnicity results provided by AncestryDNA. She gets right to the point when she writes, “the way they refer to the results is confusing.”
Kate, you are not alone. Many genealogists have been lured into taking the autosomal DNA test at one of the three major DNA testing companies just to get this glimpse into their past. Remember that the autosomal DNA test can reveal information about both your mother’s side and your father’s side of your family tree. Many take the test hoping for confirmation of a particular ancestral heritage, others are just curious to see what the results will show. Though their purposes in initiating the testing may vary, the feeling of bewilderment and befuddlement upon receiving the results is fairly universal.
Kate has some specific questions about her results that I think most will share. Let’s take a look at a couple of them. First up, Kate wants to know if our family tree data in any way influences the ethnicity results provided. The answer is an unequivocal “no.” None of the testing companies look at your family tree in any way when determining your ethnicity results. However, the results are dependent on the family trees of the reference population. The reference populations are large numbers of people whose DNA has been tested and THEIR family history has been documented for many generations in that region. The testing companies compare your DNA to theirs and that’s how they assign you to an ethnicity (and place of ancestral origin?).
Next Kate asks, “Do they mean England when they report Great Britain?” Or to put it more broadly, how do these testing companies decide to divide up the world? All of the companies handle this a little bit differently. Let’s look at Ancestry as an example. When you login to view your ethnicity results, you can click on the “show all regions” box below your results to get a list of all of the possible categories that your DNA could be placed in. These 26 categories include nine African regions, Native American, three Asian regions, eight European regions, two Pacific Island regions, two West Asian regions, and then Jewish, which is not a region, per se, but a genetically distinct group.
Clicking on each individual location in the left sidebar will bring up more information on the right about that region. For example, clicking on Great Britain tells us that DNA associated with this region is primarily found in England, Scotland, and Wales, but is also found in Ireland, France, Germany, Denmark, Belgium, Netherlands, Switzerland, Austria, and Italy. Basically, this is telling us that people with generations of ancestry in Great Britain are quite a genetic mix from many areas.
The first chart here shows that if we are to test the DNA of 100 natives of one of these primary regions (England, Scotland or Wales) then 50 of them willhave the great Britain “pattern” of DNA covering 60% or more of their entire genome, and 50 of them will have that pattern in less than 60% of their DNA. The fact that this half-way number is so low, only 60%, tells us that there is a lot of uncertainty in this ethnicity estimate because there is so much mixture in this region. Kate, for you that means that when you see Great Britain in your ethnicity estimate, it could mean England, or maybe it means Italy- Ancestry can’t be certain.
But that uncertainty isn’t the same for every region. Pictured here is also the ethnicity chart for Ireland. You can see that half the people who are native to Ireland will have 95% or more Irish DNA. Kate, for us this means that if you have Irish DNA in your results, you can be pretty certain it came from Ireland. From these tables you can see your membership in some regions is more robust than others, and Ancestry is using these tables to try to help us tell the difference.
In the end, the ethnicity results reported by each DNA testing company are highly dependent on two factors: the reference populations they use to compare your DNA against, and the statistical algorithms they use to compute your similarities to these populations. Every company is doing both of these things just a little bit differently.
Kate, if you want to get another take on your ethnicity results, you can take your data over to Family Tree DNA, or you can be tested at 23andMe. A free option is to head over to Gedmatch and try out their various ethnicity tools. If you need help downloading and transferring, you can head over to my website: http://www.yourdnaguide.com/transferring. Most people have found after searching in multiple places that their “true” results are probably somewhere in the middle.
While these ethnicity results can be interesting and useful, for most they will just be a novelty; something interesting and exciting. I have found that their most useful application is acting like a fly on a fishing line. They attract our family members into DNA testing where we can then set the hook on the real goal: family history.
If you’re ready to bait your own hook, I recommend you check out my series of DNA quick guides. These guides will help you choose the right DNA tests for your genetic genealogy questions. You’ll become a smart shopper, more prepared to choose the testing company that’s right for you. And you’ll be prepared to maximize your results from each company, rather than look at them blankly and wondered what the heck you just spent that money on.

Congratulations to Amanda, the winner of our Family Tree Magazine Digital Subscription Giveaway!
We did the giveaway to celebrate my article in the December 2013 issue of Family Tree Magazine, co-written with Genealogy Gems Contributing Editor Sunny Morton. The article is all about collaborating on our genealogy research.
I think it’s cool that Amanda’s big on collaboration herself. She blogs about her research at ABT-UNK. (Yes, that’s the name of her blog: it combines two common genealogy abbreviations for “about” and “unknown.”) Amanda points us to a recent post, “a really good example of collaboration via my blog. The two photos in the post http://www.honeytraveler.com/pharmacy/ were provided by two cousins of different degrees who found me via my blog, and five different people (so far) have been involved in identifying the people in the “Christmas Cousins” picture. I’ve connected with lots of other kin who found me via my blog (including a distant cousin in Lithuania, who helped me break through a brick wall there), and they have provided a wealth of information and wonderful photographs!”
Congratulations, Amanda, both on winning our giveaway and on your excellent research and blog. Keep it up! And thanks to Family Tree Magazine Editor Diane Haddad for donating the subscription.
These records will likely provide you with the first and last names of couples, petition date, who filed for divorce, and a case file number.
