The Genealogical Proof Standard tells us that we need to conduct reasonably exhaustive research in order for our work to be credible. If you’ve ever wondered just what constitutes “reasonable” (and if your family tree is up to snuff) my guest author Kate Eakman,professional genealogist at Legacy Tree Genealogists, has answers.
Professional Genealogist Kate Eakman explains evidence on the Genealogy Gems blog.
Genealogical Evidence: Have You Got What It Takes?
How do we know when we have compiled enough evidence to constitute proof?
Is a birth certificate or an autosomal DNA test result sufficient to declare this person is the child of that person?
Must we collect every record regarding an individual – the deeds, the tax lists, the newspaper clippings, the census reports – before we can declare a familial connection?
The Genealogical Proof Standard (GPS)
The Genealogy Proof Standard (GPS) directs us to perform reasonably exhaustive research, which requires that we identify and review all available records related to an individual.[1] This is being as thorough and accurate as possible and is a goal toward which we should all aspire in our genealogical research.
But, let’s be honest: most of us do not want to spend weeks or months (or even years) documenting one person before moving on to the next individual. We don’t want to know every detail of grandpa’s life before we turn to grandma.
We want to build a family tree which accurately provides us with the names of our ancestors so that we can identify our immigrant ancestor, or join a lineage society, or enjoy the satisfaction that comes from a balanced tree extending back a hundred years or more.
We want to be thorough and accurate, but we also want to make some progress. How do we balance the need for accuracy with the desire for results? How do we determine the necessary quality and quantity of evidence for our research?
Below are some guidelines to demonstrate how we can go about compiling the necessary information to say with confidence “this person is my ancestor.”
Genealogical Evidence Guidelines
1. One record/source is never enough.
Any one piece of data can say anything. A mother might lie on her child’s birth certificate for a number of reasons. A grieving spouse might not correctly recall the information for a husband or wife’s death certificate. There are typos and omissions and messy handwriting with which to contend. Even a lone DNA test is not sufficient evidence to prove a family connection.
We need multiple sources, and different kinds of sources, which corroborate the details of the others.
A single source is not enough. A marriage license does not guarantee that John and Griselda married. Photo courtesy https://newspapers.com.
A census report and autosomal DNA test results.
A deed and a will.
A birth certificate and an obituary.
Or, better still, a birth certificate, a census report, a deed, a will, an obituary, and autosomal DNA test results.
2. The more contemporary the source is to the person or event in question, the better.
Records of events made immediately after the event tend to be more accurate, and provide better details, than records created months or years later. As time passes, details become fuzzy, two events can be confused with each other, and our memories fade.
The passage of time between an event and the record of the event also allows for some revisionist history to creep in.
Here are some examples:
A birth year is adjusted to make someone appear older or younger in order to avoid the draft, enlist in the military, mask a dramatic age difference between spouses, or conceal an out-of-wedlock birth.
An obituary ignores the deceased’s first marriage because of some embarrassment associated with that marriage.
A census report enumerates everyone in the household as natives of Stepney, London, when they really were born in Stepney, and Hackney, and Whitechapel, which explains why the baptismal records can’t be found in Stepney.
According to this obituary for Griselda, she was the widow of Willis Tenney, not John Wise. It appears Griselda and John did not marry after all. Photo courtesy https://newspapers.com.

This is particularly true when it comes to autosomal DNA testing. My autosomal DNA is more useful for identifying my ancestors than is my son’s because I am one generation closer to those ancestors. This is the reason we encourage people to test the oldest members of their family first: their DNA has the potential to be the most useful simply because they are from an earlier generation (or two).
3. It is okay to make appropriate assumptions, but be careful!
In genealogical research we must sometimes make assumptions. When research theories are based on logical reasoning, it is perfectly acceptable to make those appropriate suppositions.
Determining which assumptions are appropriate can be simple: the two-year-old child enumerated in the home of a 90-year-old woman in the 1850 census can safely be eliminated as a biological child of that woman; the man born in 1745 could not have been buried in 1739; the person with whom I share 3150 cM of DNA is my sibling.
The challenge is to avoid making what seems like an appropriate assumption but is really based on faulty reasoning or bias. For instance, we presume that every child listed in a household in the 1860 U.S. Census is son or daughter of the two adults listed first. However, the household could include step-children, cousins, or individuals not even related to the family who were erroneously assigned the same surname.
Other inappropriate assumptions can include:
the notion that a baby was born within a week of his baptismal date;
a woman’s reported surname on her marriage certificate is her maiden name;
there is only one person in any village, town, or city with the name of your ancestor;
someone who shares 2000 cM of DNA with you must be your grandparent, aunt or uncle, niece or nephew, half sibling, or grandchild (they could be a ¾ sibling, the child of one of your parents and the sibling of the other parent).
4. All of the data from the various sources must correlate, and there can be no unresolved contradictions.
When the birth certificate says Richard was born in 1914, the 1938 newspaper article about his wedding reports Richard was 24 years old and the 1942 World War II Draft Registration card notes Richard’s date of birth occurred in 1914, we can confidently declare Richard was born in 1914.
If the wedding article declared the groom was 23 years old the contradiction could be explained by the time of year in which the wedding occurred – before or after Richard’s birthday.
But if his birth certificate reported a 1914 birth, and the newspaper article noted Richard was 32 years old, while the World War II Draft Registration listed his year of birth as 1920, we have some important contradictions. It is most likely the records are for three different men with the same name.
By collecting additional evidence, we finally learn that Griselda and John Wise did marry, and after his death Griselda married Willis Tenney. If we had collected only one of these four records we would not have had the most accurate information regarding Griselda Paul. Photos courtesy https://familysearch.org.
It’s important to remember that once we have accomplished that initial goal of building out our tree a few generations (or identifying our immigrant ancestor, or determining if we are related to that historical person) we can – and should – go back and collect other sources related to that person. This will result in uncovering a more complete story of their lives in the process.
As we can see from the four documents regarding Griselda Paul’s marriages, her story is much more than a simple list of birth, marriage, and death dates. As we identify, review, and analyze the other available sources, Griselda’s story will come alive with the facts and details we uncover.

Family History: Genealogy Made Easy Podcast with Lisa Louise Cooke Republished May 6, 2014
Listen to the Family History: Genealogy Made Easy podcast by Lisa Louise Cooke. It’s a great series for learning the research ropes and well as refreshing your skills.
Welcome to this step-by-step series for beginning genealogists—and more experienced ones who want to brush up or learn something new. I first ran this series in 2008-09. So many people have asked about it, I’m bringing it back in weekly segments.
Episode 30: Immigration and Naturalization Records for Family History, Part 2
This episode continues last episode’s conversationabout immigration and naturalization records. With me again is Stephen Danko, PhD, a genealogy lecturer and a very popular blogger. In today’s show Steve and I talk more about passenger lists, and some of the ramifications of an immigrant being detained or deported. We cover the multi-step naturalization process and you’ll hear about a fantastic find in naturalization papers–so fantastic that other researchers at the Family History Library in Salt Lake City wanted a copy!
Here are my favorite take-away points from this episode:
There were no requirements to keep passenger lists in the U.S. before 1820, or in Canada before 1867. (Many people originally arrived in one or the other of these countries, then migrated across the border, which was essentially unregulated before the 1890s.) There may have been records kept, but you’re not going to find them easily.
The passenger lists we’re most familiar with were filled out in the port of departure, then surrendered to U.S. government officials upon arrival. But other records were maintained at the port of departure. Departure information from European ports is often available on microfilm at the Family History Library, on Ancestry.com or other websites. Some of the passenger steamship lines themselves kept departure lists, like the White Star Line or the Red Star Line, and these are on microfilm. Here’s an excellent article on Passenger Departure Lists of German Emigrants, 1709-1914. Look for resources specific to other countries in genealogical guides under the headings “emigration” or “departure lists.”
Immigrants who were deported or even detained for further investigation, the steamship line had to pay the bill. If they were detained or they went back, the date and ship of deportation may be indicated on the passenger manifests.
Naturalization was a multistep process. The “first paper” is the declaration of intent. After a certain period of time, they applied for their petition for naturalization (“second papers”). Eventually they received their certificate of naturalization. After 1926, there may also be a certificate of arrival. (See Episode 29.)
Naturalization records may be at the county level or may be in federal court. Increasingly these are coming online. Meanwhile, some are easier to track down than others. Most Massachusetts naturalizations are available on microfilm and at the Massachusetts State Library. Some books
Many 20th-century naturalizations are packed with family information. Steve shared an example for one of his relatives. Her naturalization had her name, birthdate and birthplace, name of her husband and date of her marriage, her husband’s birthplace and date, the names of all her children, her date of arrival and the ship she came on! Some later naturalizations also have photographs. Microfilmed files may also have the certificate of arrival.
Updates and Links
About 70 million immigration and naturalization records have been indexed in recent years through an enormous community indexing project led by FamilySearch. Check out their site (below) to see what records are searchable now.
At some point in the past, many of our relatives–overseas or in the same land–spoke a different language. They used different versions of names we know. Records about their lives were created in a language we don’t know, whether their home tongue or the language of an institution, like church records in Latin.
Well, MyHeritage has just launched a groundbreaking new technology today that aims to remove language barriers in family history research. “Global Name Translation™ helps overcome the Tower of Babel syndrome,” says Gilad Japhet, Founder and CEO of MyHeritage. “The world is getting smaller and more connected, yet information from other countries is still mostly hidden from those who don’t speak the language.
Now you can now search for historical records at MyHeritage “in one language and receive relevant results from other languages, automatically translated for you into the language of your search,” explains Japhet. For example? “A search for Alessandro (Alexander in Italian) will also find ‘Саша’ (which is the Russian form of Sasha, a popular nickname of Alexander in Russia) with its corresponding transliteration into the language of your search.”
This technology is also integrated into MyHeritage matching technologies, so subscribers will begin receiving transliterated matches from other languages.
According to a press release, Global Name Translation™ works with “very high accuracy, generating all the plausible translations, to facilitate matches between names in different languages. In addition, a manual search in one language will also provide results in other languages, translated back to the user’s language for convenience. This is a unique innovation not offered elsewhere, useful for anyone interested in discovering their global roots.”
The first version works with several languages: English, German, Dutch, French, Spanish, Catalan, Portuguese, Italian, Norwegian, Swedish, Danish, Greek, Hebrew, Polish, Czech, Russian and Ukrainian. “The next version currently in development will add Chinese and Japanese, and additional languages will follow.”

Thousands of historical maps of New York City, the mid-Atlantic states and even the Austro-Hungarian empire (yes, really!) are now online–and they’re free.
The New York Public Library has published more than 20,000 historical maps dating from 1660-1922. They are free for public use, downloading, manipulating and publishing! A lot of the maps are from New York City neighborhoods, like the one shown here.
The author of a news item about the collection said this: “We can’t imagine too many people wanting to remix Gangs of New York-era property charts, but it’s hard to object to getting more geographic knowledge at no charge.” Well, we genealogists may not “remix” these old property maps, but we can certainly see the value in them!
Welcome to this step-by-step series for beginning genealogists—and more experienced ones who want to brush up or learn something new. I first ran this series in 2008-09. So many people have asked about it, I’m bringing it back in weekly segments.
We’re going to start off today by continuing our use of U.S. Federal Census Records. Last episode we located relatives in the 1930 census, and today we’re going to push further back in time to follow the census bread crumb trail.
Then in our second segment we’re going to explore some census enumerations that often go overlooked by family historians with Curt Witcher, the Manager of the nationally-recognized Genealogy Center at the Allen County Public Library in Fort Wayne, Indiana. Curt is a very well-known genealogy lecturer and he has some great tips for tapping in to more obscure census resources. We’ll talk about nonpopulation schedules for the federal census, census substitutes for missing census data (like the 1890 census) and state censuses that may be available, too.
Updates and Links
As I mentioned in the show notes of the last episode, the 1940 census is now available to researchers. Check out those notes for more information. Here are some more updates and links:
The U.S. Census Bureau has online info on state censuses. Learn even more in Ann S. Lainhart’s book State Census Records (Genealogical Publishing Company, 1992). A lot of state censuses are now searchable on Ancestry.com and FamilySearch.org.
A few fragments of the 1890 census remain. These are searchable at Ancestry.com and FamilySearch.
The Ancestry database substitute for the 1890 census I mentioned in the show is now supplemented by census substitute databases on Ancestry for just about every state for 1890 and other years. Search for them in the Card Catalog with the search term “1890 census.”
