AncestryDNA Communities and the Benefits of Testing the Oldest Generation

I look forward to learning about the new tools and updates that come from DNA testing companies. Recently Ancestry.com updated their genetic communities. Genetic communities demonstrate the link between genetic genealogy and traditional documentary genealogy research. Ancestry uses the family trees of customers and the power of their massive autosomal DNA database (over 21 million testers) to place groups of ancestors in a place and time. The time frame (starting about 300 years ago) matches the time period when documentary evidence might be found. DNA communities provide hints for further research.

Autosomal DNA inheritance is random and siblings (unless they are identical twins) will have different results. My brother and I each received half of our atDNA from our dad and half from our mom, but we didn’t get the same half.

My results aren’t very impressive:

My DNA Communities from Ancestry.com

I have one community. Clicking through the information tells me which DNA matches and which ancestors fit in this group.

Here are the results for my brother:

My Brother’s DNA Communities from Ancestry.com

The DNA Community for my brother is different than the one I have. One of the same 4x-great grandfathers on my maternal side, Holloway Key (1777-1855), is in both groups. This makes sense since the geographic area of Tennessee where he settled appears in both. For my paternal side, there are hints I can pursue in the Lower Midwest & Virginia Settlers group for the House family that I am curious about.

I tested my mother before she passed away, and her brother (my maternal uncle) also agreed to test. That puts me one generation closer to my maternal ancestors.

Here are my mother’s results:

My Mother’s DNA Communities on Ancestry

Not only does my mother have the DNA community my brother had, Southern Midwestern Settlers (his is orange, hers is green), she has four others.

My uncle provided an additional community, Early Upper South Settlers:

My Maternal Uncle’s DNA Communities on Ancestry

The results differ a little, and that’s because of the different autosomal DNA they inherited from their parents (my maternal grandparents). The number of new communities demonstrates the rich genetic information older generations hold.

Here’s a comparison of the results for the four of us:

South Central Appalachia Settlers (1700-1950) North Carolina High Country Settlers  
Southern Midwestern Settlers (1700-1975) 
Comparison of DNA Communities for My Mom, My Maternal Uncle, Myself and My Brother at Ancestry

The text describing the community, animated maps showing migration patterns, and hints from Ancestry provide clues that I can research. We don’t know anything about my maternal 2x great-grandmother, Mattie (Childres) Fisher Pike Adams outside of 3 marriages and 1 census. Ancestry placed this branch in the “Arkansas, Oklahoma and Texas Settlers” with origins in Northwestern Europe and the British Isles, possibly migrating to the Chesapeake Bay area and moving across Tennessee and Kentucky. This is consistent with the Childres matches I am researching.

If I did not have my mother and my uncle, I would I would be missing five genetic communities. Perhaps in the next update, the DNA communities will show up for my brother and me. I welcome the new clues in my search for Mattie’s family.

Celebrating with the Virtual Genealogical Association (VGA)

We celebrate far too little. So when the VGA asked me to come to the party, I said, “yes!”

I spent 3 hours today with fellow family historians. We heard from great speakers who shared fun tips and told interesting stories. We played genealogy games, too! I shared my version of a much-loved evening game show that involves responding to an answer with a question. Yes, that’s the one! Everyone had a blast and we had a winner who excelled at the Genealogical Proof Standard Category.

The sponsors recorded the presentations and shared additional presentations on their YouTube Channel. I contributed two recordings: Concise Communication for Genealogists using SBAR and an Introduction to WikiTree’s US Black Heritage Project. Head on over to listen to my recordings and hear all the wonderful presenters.

What a fun party!

National History Day provides inspiration and hope

For many years I have served as a volunteer for National History Day (NHD). NHD began in Cleveland in 1974 with students participating in the equivalent of a Science Fair for history. Participants develop research questions, conduct research, analyze information, and write conclusions based on a theme that changes annually. The originator, David Van Tassel, hoped to help younger students see the relevance of history in their lives. By 1976 the competition spread statewide and within four years it was nationwide. Currently, around 500,000 students participate each year, supported by 30,000 teachers. Students may participate in NHD at local, regional, state, and national levels. The strongest projects advance throughout the levels. Students choose to participate individually or in a group. Individuals submit papers, websites, documentaries, performances, or exhibits. Groups can submit websites, documentaries, performances, or exhibits. You can view examples here.

My daughter dove into history day in 8th grade and in 10th grade represented Washington State at the national contest in Maryland. As a History Day parent, I provided transportation and the occasional feedback upon request. Significant adult help is forbidden. I served as a chaperone for the national competition. Imagine a college taken over by hundreds of students excited about history, some of them wandering around in costume for their performances, and all cheering their state team. About ten years ago I first volunteered as a judge. Judges receive an orientation to the rules and processes of the contest and use rubrics to rank the projects in teams.

For the last couple of years I’ve participate virtually as a judge. I’ve judged documentaries and websites from home. Every year I learn from each of the thirteen or so student projects I review. This year’s theme is “Debate & Diplomacy in History: Successes, Failures, Consequences.” The creativity of the students amazes me. They locate primary documents, interview experts, communicate their thesis, and analyze their findings. The skills they learn through NHD will aid them in future endeavours. 

If you are interested in volunteering, you can find the organization in your state by checking out the affiliate links. I’m so grateful for these students who teach me, fill me with hope, and inspire me.

Exploring the 1950 U.S. Census

Like any avid family history researcher or professional genealogist, I had known for years that the 1950 US census would be released on 1 April 2022. As the release date drew near, the number of articles, presentations, and blog posts about the 1950 census grew exponentially. Many people prepared to spend hours searching for their families starting at the stroke of midnight. I wasn’t among them. Why? I anticipated the website crashing under the weight of so many people trying to access the database. I might also have decided to go against the grain and not get caught up in the drama. Part of me wanted to learn from everyone else who went first. What I learned was that it was a rousing success so I set aside some time this morning to explore.

Background on the 1950 census

The 1950 census is the first census to be released with Machine Learning and Artificial Intelligence technology. A machine reviewed the census and created a searchable database of names based on interpretation of handwriting. That’s amazing! It’s a far cry from the days of using the Soundex and microfilm in a dark room at the National Archives poring over faded copies for hours. It’s not quite what researchers have become accustomed to: a census that is indexed and easily searchable on more than one website. That’s coming soon.

Based on early ideas about using the 1950 census, I was prepared to spend hours looking for the Enumeration District (ED) where I thought my family might be. The machine-derived index made that irrelevant for my first searches. The index will be updated with human effort over the upcoming months. Indexes for the first two states, Wyoming and Delaware, have been released at MyHeritage. Ancestry and FamilySearch also have the images available and are working on indexing. Each company has unique search capability and index. Whenever you can’t find your family in an index, before giving up or resorting to reading each page, check an index at a different website.

For the machine-derived index, keep in mind that enumerators recorded information by household. Typically, the surname appears next to the head of the household and usually a straight line or nothing is written for subsequent family members of the same surname. That meant I wouldn’t be looking for my father and mother who were children at the time. I would be searching for my grandfathers.

The challenge: How long would it take to find my parents?

The two surnames I was searching for, Davis and Johnson, are incredibly common and my family wasn’t living in rural or remote areas in 1950. I was prepared to slog my way through reading many pages before I found them. Before I began, I reviewed a useful article by Teresa Koch-Bostic which is available for members of the National Genealogical Society. Then I started my timer.

Finding Dad: 9 minutes and 26 seconds

Here are my steps and what I found:

  • I reviewed my father’s timeline from my genealogy software, Reunion. I knew the family lived in Hollister, San Benito County, California. My dad graduated June 1952 from San Benito County High School.
  • I entered the National Archives website and clicked on search.
National Archives 1950 Census Welcome Page
  • I completed the information I had for state, county, and name, entering California, San Benito, Walt Davis (my grandfather’s name, the head of the household). I soon realized that Last Name, First Name order would be an improvement, but not crucial to success. I also noticed that the machine picked up the name David for Davis (see red arrow below), which is a good thing, since terminal letters in handwriting are often difficult to decipher. I switched my strategy and re-entered the name as Davis Walt. (His full name was Walton but he often went by Walt, and sometimes was confused with Walter, his father.)
1950 Census Search for “Davis Walt” in San Benito County, California
  • I scrolled the results and the 26th name I encountered was my grandfather, Walton Davis. The family appeared on the bottom of page 1 and the top of page 2.
1950 U.S. census, San Benito County, California, ED 35-2, page 1
1950 U.S. census, San Benito County, California, ED 35-2, page 1 with my father enumerated as “Alvaughn Hale Davis” (red arrow)

A close review of the page revealed the amount of information captured in the census. Although none of the information surprised me, seeing the names of my grandparents, uncle, and father, all gone now, made me smile. My grandmother’s stories of the auto dealership and garage sprang to mind and I could almost smell the oil and gas and see my grandfather disappointed with his challenges in receiving the type of cars he wanted to sell. I could picture my 16-year-old dad and his 17-year-old brother in coveralls with flat top haircuts, pumping gas and working in the garage.

My next step was to record the information in Reunion. The data entry took an additional 15 minutes because I created a new citation template for the 1950 census and added other useful information from the census to all the family member’s profiles. I updated my grandfather’s WikiTree biography and I will need to do the same for the rest of the family members.

Finding Mom: 1 minute and 47 seconds

I repeated the strategy for my mother, looking for my maternal grandfather, (in reverse order) “Johnson Lindell,” in Dyer County, Tennessee. Bingo! Six names down the list, there he was, along with his entire family (including my mother) at 420 Kist Avenue, the house I remember from my childhood (see arrow number 1, below). My great-uncle, his son and my great-grandmother all appear to be at the same house number, but I believe the second house was already on the property at that time. I’ll have to ask my uncle. My grandfather worked at the cotton mill down the street, as did my Aunt Earline, on line 22 (enumerated as Mildred E. Coleman.) A couple of their neighbors also worked at the mill. My great uncle A.W. (line 25, household 87) was delivering pottery. I grew up using the peach-shaped sugar bowl my mother received from his time driving the pottery truck.

Two family members appear in the supplemental information at the bottom of the page (arrow #2). The census used a sampling strategy and enumerators recorded additional information for every fifth person on the census. My uncle L.S. was on line 18 and my cousin Jimmy was on line 23. The corresponding lines in the bottom section show information about residence in past year, nativity of parents, schooling, work, income, and military service. The information for Uncle L.S. is interesting. He was 16 years old and the information indicates he had completed 4th grade and did attend school in 1950. He is over 14 but the next section is blank, when the section header indicates it should be filled out for anyone 14 or older. His enumeration data above on line 18 noted he was working, delivering papers. Jimmy was two, so the information for him isn’t very revealing. Important information may be here in other situations. It could be the impetus for searching military records, understanding the family’s social situation, or the key to discovering an immigration pattern.

My examples were simple cases. I knew the exactly where the families were living and both were reasonably-sized communities. I knew the address of one place but I didn’t need it. If I were doing research on a family that relocated often and was in an urban setting, my results would have been different.

Your turn!

I’m looking forward to catching up on other family members in 1950. I don’t have any burning questions right now about my family in that time period, so it’s likely I will coordinate gathering 1950 census information as I improve the biographies of my family on WikiTree. And the data might be important for upcoming client work. I’m glad I took the few short minutes to explore the 1950 census. I’ll be back soon!

Happy searching!

Nefarious Use of the 1840 U.S. Census

Genealogists commonly encounter errors in census data. But what about the deliberate misuse of census data to cause harm? The 1840 census illustrates how census data were used for ill.

Family historians rely on information from census records, hoping to identify family units and to trace location and situation over time. The 1840 census, like those from 1790 to 1830, documented families under the name of the head of household and counted other household members by age, gender, race, and status of free or enslaved. The informant was unknown and could be the enumerator, a neighbour, or any member of the family.[1] Over time, the data collected for each census varied, depending on the priorities of the government. Data from the first census in 1790 determined Congressional representation and funding for the new government.[2]

As the government’s need for information grew, the census data accommodated that need. By 1820, naturalization status and involvement in agriculture, manufacturing or trade were assessed.[3] Collection of information about health or functional status began in 1830 with enumeration of those who were deaf, deaf mute, or blind. In 1840, the enumeration included those insane (referring to people with mental illness) or idiotic (referring to those with developmental or intellectual disabilities) and if they were supported by private or public means.[4]

Selected 1840 Census Headings

As any family historian knows, the information in the census can be flawed at the individual level. The misinformation may have occurred at the time of enumeration, with ages guessed, misstated, or misunderstood. Location information is primary and most reliable, since the enumerator went from dwelling-to-dwelling collecting information. Errors could be introduced during transcription since each enumerator created multiple copies. Fraud by the enumerator was also a possibility.[5] Data were recorded across large sheets in columns. Standardized forms introduced in 1830 improved collection of census data.[6]

Congressional reports collated census data to inform policy, and the 1840 census was no exception. The Compendium of the Enumeration of the Inhabitants and Statistics of the United States, as Obtained at the Department of State, from Returns of the Sixth Census supported arguments of politicians in slaveholding states because it reported that the percentage of “colored persons” who were “insane and idiots” was higher in northern states compared to southern states.[7] The statistics showed that “the negroes and mulattoes of the north produced one lunatic or idiot for every one hundred and forty-four persons, while the same class at the south produced only one lunatic or idiot for every fifteen hundred and fifty-eighth.”[8] Politicians like Senator and former Vice President John C. Calhoun of South Carolina claimed that slavery benefited “the African race.” In an 1837 speech he said, “I may say, with truth, that in few countries so much is left to the share of the labourer [referring to enslaved people], and so little exacted from him, or where there is more kind attention to him in sickness or infirmities of age.”[9] The census bolstered Calhoun’s pro-slavery politics and his personal finances as an enslaver. The John C. Calhoun household in 1840 included seventy-seven enslaved people.[10]

Dr. Edward Jarvis, a specialist in treating mental disorders, used the time he was convalescing from a broken leg to study the 1840 census records. Jarvis reviewed the entire census and recalculated the totals, noting multiple errors in the tallying of the data for free colored people.[11] An example is the census of the community of Scarborough in Cumberland County, Maine. No free people of color were enumerated in Scarborough, but the totals include 6 “colored persons” who were classified as “idiots and insane” as shown in the image below.

1840 Census of Scarborough, Cumberland County, Maine

Jarvis determined that the Worcester, Massachusetts enumeration contained a more flagrant error. The totals page, shown below, noted 133 “colored persons” who were insane or idiots and cared for at public expense. The entire “free colored” population shown on the prior page was 150. Dr. Jarvis’ investigation revealed that the 133 people were white residents of the state hospital for the insane.[12]

1840 Census of Worcester County, Massachusetts

Jarvis’ analysis became known to members of Congress and on 26 February 1844, John Quincy Adams brought a resolution to the House of Representatives that the “Secretary of State be directed to inform the House whether any gross errors have been discovered in the printed …census…[of 1840]…and, if so, how those errors originated, what they are, and what, if any, measures have been taken to rectify them.”[13] On April 10 1844, John C. Calhoun was appointed Secretary of State and on 6 May 1844, he responded to the House Resolution of 26 February “stating that no such errors had been discovered.”[14] Efforts to address the errors continued for decades, with Jarvis continuing to publish and refute publications that cited the erroneous data.[15]

The 1840 census errors remain.[16] John C. Calhoun used the results of the faulty census to justify slavery to the British government, who had pressured the United States to abolish slavery in Texas.[17] A report in 1900 concluded that errors were present in 1840 and attributed the errors to “ineffectiveness of the machinery by which the census was then taken” including the amount of data being collected, inadequate compensation, and improper supervision.[18] That these errors remain serve as a testament to people who would misuse data to further the ill treatment of other members of society, such as the enslavement of 2,487,355 people counted in the 1840 census.[19] As family historians, our experience with individual errors can help us understand how the magnification of errors combined with nefarious political actions furthered the cause of enslavers and underpins myths that survive to this day.
