I’ve always been a fan of what used to be called “Citizen Science” and has recently been re-named “Community Science.” I contribute birding data to ebird. I was a volunteer atlasser for the BC Breeding Bird Survey in its early days and I continue to support my husband on the annual survey. We start at the crack of dawn and he counts birds while I drive and keep the tally.
I’m excited to have the opportunity to support genetic genealogy. Blaine Bettinger, the genetic genealogist who is behind the Shared cM Project on DNA Painter, has opened submissions for the next update. The goal is over 100,000 submissions. He hopes to release the update in early 2023. Now’s the time to contribute! There are two ways to do it.
Through this spreadsheet link which is a great option of you have a lot of data.
If you are unfamiliar with the Shared cM Project, it is the go-to place to check genetics vs. genealogy. That’s the step in the analysis when you see if you and your DNA match share the amount of cM that will help you confirm or figure out a relationship. You can get these predictions from each of the testing companies. That’s the notation by your match that says “2nd-3rd Cousin.” Each company uses their own data and information, which could be based on faulty trees. What’s different about the Shared cM data is that it is crowd-sourced. Genealogists who have confirmed the relationships through documentary research provide the data. That’s us! This will be my third time contributing data.
The latest genetic genealogy features and tools bring excitement and potential for new insights. The combination of Ancestry’s Ethnicity Inheritance Chromosome Painter and Jonny Perl’s ACPS (Ancestry Chromosome Painter Segments) tool allows comparison of Ancestry data with information from other testing companies. Jonny’s new tool uses the information from Ancestry to grab <<gasp>> segment data <<gasp>>. It’s not the segment data you’ve been hoping for (segments shared with matches) but it’s fun and potentially useful depending on your situation.
Several months ago, Ancestry released ethnicity results with “Side View” technology. Side View allows you to see which ethnicity you received from each of your two parents. Unless you’ve had a parent tested or recognize which parent is which, the two parents are simply labelled “Parent 1” and “Parent 2.” You can label them yourself.
Here’s my mother’s ethnicity split into the contributions from her two parents.
Ancestry Ethnicity Inheritance Overview Showing ethnicity for each parent of my mother
Ancestry is now rolling out the beta feature of a chromosome painter for ethnicity, catching up with 23andMe and FamilyTreeDNA who already offer this feature.
My mother’s results on Ancestry look like this:
Ancestry’s Ethnicity Inheritance Chromosome Painter for my mother
Each numbered pair represents my mother’s chromosomes, 1-22 (chromosome 23 is the chromosome that determines biological gender and Ancestry does not show the results of chromosome 23.) One chromosome of the pair is from my mother’s dad and one chromosome from her mother. The different colours represent different ethnicities, which refer to geographic locations. As you can see, my mother’s ancestry is primarily European, and largely from England and Northwestern Europe. As of this moment, I don’t know which of the two (upper or lower chromosome) is my maternal grandfather and which is my maternal grandmother. My mom has three segments labelled “Indigenous Americas-North” and one labelled “Southern India.”
My maternal uncle’s Ancestry Ethnicity Inheritance Chromosome Painter results look like this:
Ancestry’s Ethnicity Inheritance Chromosome Painter for my maternal uncle
Notice the colours in the key are not stable, which is a shortcoming of the Ancestry Chromosome Painter and their ethnicity results in general. It would be useful for Norway to be the same colour no matter whose DNA test I am looking at. Norway is blue for my mom and purple for my uncle. And then there are the two shades of purple that are similar – Norway and Indigenous Americas for my uncle. And all the shades of green, aqua, blue, darker aqua… more variety would be helpful. I’m grateful for the information and I can edit the colours when I move the segment data to DNA Painter using Jonny’s new tool. My uncle has four segments labelled Indigenous Americas. They are on chromosomes 3, 4, 6, and 12.
Here is my maternal aunt:
Ancestry’s Ethnicity Inheritance Chromosome Painter for my maternal aunt
My aunt has a new category, Germanic Europe, and two Indigenous America’s segments. When comparing the three images, it’s important to remember that Ancestry randomly assigned Parent 1 (upper chromosome) and Parent 2 (lower chromosome). My mother’s seems to be reversed from her siblings since the “Indigenous Americas” segment on chromosome 3 is Parent 1 for my mom and Parent 2 for my uncle and aunt.
Jonny Perl’s new tool allows me to copy and paste the data that creates the Ancestry image and make a file I can manipulate at DNA Painter. (To learn how to use DNA Painter, there are several good webinars with demonstrations and resources here.) Jonny used known information about DNA to approximate the start and stop points from the Ancestry chromosome images to make this work.
Ethnicity results can be compared across the companies. Remember my uncle who had several chromosomes with Indigenous Americas on Ancestry? Here I’ve uploaded his FamilyTree DNA ethnicities on the same DNA Painter diagram as his Ancestry ethnicity. I’m showing the detail for chromosomes 3 and 4.
FamilyTree DNA and Ancestry Ethnicity results compared for my maternal uncle
FamilyTree DNA results for both maternal and paternal chromosomes are mapped to “Shared or Both” because I don’t know which chromosome is maternal and which is paternal. Ancestry DNA chromosomes are artificially labeled maternal and paternal. FamilyTree DNA uses fewer ethnicity labels than Ancestry. Nearly all of my uncle’s DNA is labelled “Western Europe” and shows up as a darker pink bar. Ancestry separates “England & Northwestern Europe” shown in green and Scotland in aqua. FTDNA’s “Americas” segments in green are not as extensive as the approximated “Indigenous Americas-North” from Ancestry via Jonny Perl’s new tool. This may change if Ancestry ever allows a real download of raw ethnicity data. The Indigenous Ancestry is a small percentage of my uncle’s DNA but seeing it detected by both companies increases my confidence in the segments.
The segment on my mother’s chromosome 5 that is attributed to Southern India caught my attention. I’ve painted matches from GEDmatch, MyHeritage, and FamilyTreeDNA to DNA Painter. (My mom is not on 23andMe, which is the other testing site with segment data.). I was curious to see if there were any matches corresponding to that unusual segment.
Chromosome 5 ethnicity and matches for my mother
Remember that the Ancestry ethnicity segments which are imported as maternal or paternal could be the other way around. In this case, there is an unknown maternal match for SC (in bright pink) that does seem quite similar to the Southern India segment. I will keep an eye on this, it could be helpful in the future.
I’m encouraged by the new developments and hope they unlock mysteries for you.
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:

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.
