Do you need help solving your family migration patterns? A groundbreaking new scientific study uses DNA and family trees to map migration routes across North America.
Family Migration Patterns Revealed in Genomes
A new study published in Nature Communications represents a ground-breaking development in using DNA for genealogy. The article from the AncestryDNA Scientific Team is titled Clustering of 770,000 genomes reveals post-colonial population structure of North America. Or, in more understandable terms, “Your DNA can tell us where you came from in America in the last 500 years.”
Wow, right? So, how did they do this?
The power really is in the numbers. In this particular paper, they started with using their autosomal DNA test on 770,000 people. Some of them were AncestryDNA customers who had consented to be part of the research. From these 770,000, they learned quite a bit about the migration patterns of early Americans. As Ancestry analyzes more individuals using these same principles of correlating genetics and genealogy, this data will improve and be able to tell us even more about our heritage. Even though it takes a large data set to figure out the relationship between our DNA and migration patterns, it really comes down to the relationship of two people.
To start, Ancestry determines how just two people are genetically related. Then, they find how those two are related to a third person, again, looking only at pairs of people. This goes on and on until everyone in the group as been compared. They use a graph to plot those relationships, with those more closely related clustering around each other. And then it happens. The point where we see the marriage of genetics and genealogy suddenly appear by adding in the family history information for each of these individuals in the cluster.
What they found was astounding. They have displayed the data in Figure 3 shown below. It is a map of the United States with colored dots scattered across the landscape. The location of the dots corresponds to the genealogy of those tested, while the color of the dots relates to their genetic clustering. Those who cluster closest together are the same color. The result is a nearly perfect rainbow, with buy anti anxiety medication online uk each color holding its respective spot on the map, with very little overlap between groups.

We might be tempted when looking at the map to think, oh, well, of course there is a large population of European Jews in New York, everyone knows that. But this isn’t their family history, their accent, or their culture telling us this – it is their genetics!
As if that wasn’t exciting enough, the scientists describe how we can trace family migration patterns of different groups over just a few generations. They specifically mention French Canadians and Cajuns/Acadians, but the same principle can theoretically be applied to dozens of other groups.
Family Migration Patterns and Applying these Findings
So what does this mean for you as a genealogist?
It means we are getting closer than ever to being able to tell who you are and where you came from using your DNA.
For example, let’s say you have an ancestor in Texas about 4 generations ago, but you aren’t sure where she came from. Your DNA could tell you that you fit into the Lower South group, meaning that your ancestor likely hails from the south. Or, maybe your genetics identify with the Upland South, which means you need to explore records from Arkansas, Tennessee, and North Carolina.
This is just a glimpse into the advances that genetics are bringing to your genealogy toolbox these days. So it’s high time to go “all in” to learn about genetic genealogy! We recommend The Family Tree Guide to DNA Testing and Genetic Genealogy by Blaine Bettinger. You’ll love this book if:
- You’ve got brick walls that traditional research methods haven’t been able to break down
- You want to take advantage of the hottest tool in genealogy
- You’ve already taken a DNA test and want to know what comes next

Here’s the latest DNA update quoted from Ancestry®:
Ancestry® Expands Reference Panel to Deliver More Precise Results and New Regions
“Today, Ancestry® announced their latest update to AncestryDNA® ethnicity estimates.
This update was made possible thanks to an increase in the AncestryDNA reference panel.
The reference panel is now more than double its previous size with samples from more places around the world, allowing Ancestry to determine ethnic breakdowns with a higher degree of precision.
New ethnicity estimates will roll out to new and existing customers over several months, resulting in these potential developments for customers.”
New Ethnicity Regions
From their blog post:
“For example, previously we had North and South America as two large regions: Native American–Andean and Native American–North, Central, South.
With this new update, we are able to refine the areas into 11 smaller ones.
If you received one of the older regions before, your new report will most likely have one of the newer, more precise regions instead like Indigenous Eastern South America, Indigenous Cuba, and Indigenous Americas–Mexico, among others.”
More Global Regions
“This advancement will enable AncestryDNA to deliver even more regions globally to enhance the experience across diverse populations including improvements and region realignment in West Africa, northwestern Europe, the Americas, Oceania, and South Asia.”
When You Will See the Update
“It’s important to note that we are phasing the update over time to ensure individual attention is given to delivering each result; therefore, some may see results earlier or later than others.”
Read the Full Announcement
Get all the details on this new update announcement by reading their article Ancestry® Expands Reference Panel to Deliver More Precise Results and New Regions.
List of AncestryDNA® Regions
“More than 1,000 global regions make up the ethnicities displayed in our DNA test. As DNA science improves, the number of regions we test for (and the countries covered in each region) may change.
This article lists each region, but to see which areas of the globe are included in the regions, you’ll need to view the list from your DNA Story page (which will highlight an area of the map when you click a region).
To see all the regions, click See other regions tested at the bottom of your ethnicity estimate and click on a region on the next page.

by Lisa Cooke | May 5, 2017 | 01 What's New, Digital Archives, Records & databases
Millions of New England vital records are among newly-published genealogy records online. So are English parish records, Irish Easter Rising records, Italian civil registrations, South African church records, and records for Georgia WWI soldiers and Louisiana women.
New online this week are millions of new genealogy records from around the world! First, we’ll feature these (mostly) free vital records collections for New England states–but keep scrolling. We’ve got records to mention for other parts of the U.S., as well as England, Ireland, Italy, and South Africa.
New England Vital Records
New England vital records online got a BIG bump this week with the following additions:
Sample image from “Maine Vital Records, 1670-1921.” Database with images. FamilySearch. http://FamilySearch.org : 2 May 2017. Citing Division of Vital Statistics. State Board of Health, Augusta. Click to view.
Connecticut. More than 755,000 indexed names have been added to FamilySearch.org’s free collection, Connecticut Marriages, 1640-1939. This hybrid index/image collection has this note: “We have legal rights to publish most of the images associated with these records; however, there are a few records that will not have an accompanying image available for view.”
Maine. FamilySearch.org has added nearly a half million indexed names to its collection of Maine Vital Records, 1670-1921. According to the site, the collection is comprised of a “name index and images of birth, marriage, and death returns acquired from the State Board of Health, Division of Vital Statistics and the state archives.”
Massachusetts: New images have been added to the New England Historic Genealogical Society’s collection for the Roman Catholic Archdiocese of Boston, 1789-1900. The update includes the following volumes: Immaculate Conception (Salem), St. Mary (Salem), and Sacred Heart (Roslindale).
Rhode Island. FamilySearch has added over a half million new indexed names and 30,000 digital images to its free collection, Rhode Island – Vital records. These are described as “Certificates and registers of births, 1846-1898, 1901-1903, marriages 1901-1903 and deaths, 1901-1953 acquired from the State Archives in Providence.”
Other new and updated records in the US include:
- Newspapers – Baltimore MD and Hartford CT. Newspapers.com has added issues for two major papers: the Baltimore Sun (1837-2017) and the Hartford Courant (1764–2017). (With a Newspapers.com Basic subscription, you can access issues of these papers through 1922; or, with a Publisher Extra subscription, access those early years and additional issues from 1923 onward.)
- Georgia. A memorial book for Georgia soldiers who served in World War I is being updated to include the names of African-Americans who served. “Due to the social and racial conditions of the time, this Memorial Book contains the information for only white soldiers,” explains the database landing page on the free United States World War I Centennial Commission website. “The current project is rectifying this by adding information for Georgia’s African-American personnel that also died in service. Further, we are adding names found on WWI monuments and plaques that are missing from the original Memorial Book….As missing names are determined and documented, they will be added” We learned about it in this press release from the University of North Georgia.
- Louisiana. A collection of digitized publications by the Louisiana United Methodist Women (and predecessor organizations) is now free to search at the Centenary College of Louisiana Archives & Special Collections web portal (scroll down to Digital Collections and click Louisiana United Methodist Women’s Publications). According to an announcement by the college, “The digitized material includes annual reports (1884-2014) and newsletters (1963-2006) – 12,000 pages in total. Researchers can access them online, page through each volume, download complete PDFs, and search the full text versions.” Published digitized material is easy to keyword-search for ancestors’ names and hometowns. Here’s a general tip for finding married women’s names in older documents: search on just her surname or her husband’s name, as she may appear as “Mrs. Alexander Reed.”
England: Newspapers and Parish Records
The British Newspaper Archive has added two new titles, The Yarmouth Independent (a Norfolk paper, 1862-1891) and The Rugby Advertiser (a Warwickshire title, 1850s-1950s).
Subscription website TheGenealogist has published over 100,000 parish records and thousands of voter records. According to the announcement, polls books include “35 different registers of people who were entitled to vote in Wakefield, West Yorkshire and other constituencies situated in Hampshire, Gloucestershire, Somerset and New Westminster in Canada….Electoral records are taken from the official lists produced to record who was entitled to vote in the various parliamentary elections.” Among new parish record collections are “100,000 new individuals added for the County of Worcestershire and additionally the Registers of the Parish Church of Rochdale in Lancashire that covers the period between 1642 and 1700.”
Findmypast.com has added 312,000 new records to its collection of Kent marriage records. New additions are for the parishes of Bapchild, Biddenden, Kilndown, Tenterden, and Wittersham. Additionally, over 18,000 new records have been added to Kent Baptisms (parishes of Bapchild, Brompton, Chatham, New Gillingham, Wingham and Wittersham); over 3,000 records have been added to Kent Banns (parishes of Bapchild, Biddenden, and Wittersham); and over 18,000 new records are in Kent Burials (parishes of Bapchild, Kilndown, Tenterden, and Wittersham).
The site has also added to its records for North West Kent, described as “areas within the London boroughs which were historically part of Kent.” Over 23,000 records have been added to the North West Kent Baptisms collection, and another 15,000 to North West Kent Burials.
Ireland – Easter Rising and Newspapers
Findmypast.com has added over 76,000 records to its collection, Easter Rising & Ireland Under Martial Law 1916-1921. According to the site, “These once classified records, digitized from original documents held by The National Archives in Kew, record the struggles of life under martial law in Ireland and contain the details of soldiers and civilians who participated in or were affected by the Easter Rising of April 1916.”
“Your ancestor may be found in the records if they were killed or wounded during the conflict, arrested and held in internment, or tried by court martial. Additionally, if their home or place of work was searched they may appear in the records as the collection shows the efforts of the military and police to discover arms, ammunition and seditious material through thousands of raids.”
Also, Findmypast.com has added over 401,089 new articles and one new title to its collection of historic Irish Newspapers. The Ballymena Weekly Telegraph is the latest publication to join the collection and currently covers the years 1904, 1906-1916, 1921-1929 and 1931-1957.
