My family's AncestryDNA Genetic Communities


At RootsTech 2017 Tim Sullivan, CEO and president of Ancestry announced that Ancestry would be rolling out a new tool in March for those who have taken their AncestryDNA test(an autosomal test).  As the name suggests it groups your DNA matches into communities.  If you are interested in knowing more about all the research put into developing and the basis for this feature you can see that at the Genetic Communities: Whitepaper.

Expectations
What were my expectations?  In my own ancestry I have a great deal of colonial lines many of which settled in the southeastern United States.  Paternal lines I expect a good deal of English/Irish  represented in those matches.  Many of them were in Logan Co. KY, Union Co. SC and later Bedford, Rutherford and Williamson Co.,  TN.  My maternal lines are from the Isle of Man, England and Ireland.  In the states the concentration would be White, Warren and Van Buren Co TN area.  

For my daughter's ancestry my expectations were German and English with colonial communities in Georgia, East Tennessee, Alabama and Virginia.  She did have ancestors who immigrated a lot later than mine 1830s and 1890s and I expected to see communities for them in Florida and also Franklin Co Indiana.

For my sister's results I was expecting along the same lines as my own even though we have a lot of variation in what we inherited from our Dad.

Results for:


Me

Early Settlers of Northern Arkansas & Middle Tennessee
--You and 466 of your DNA matches, along with 114,564 other AncestryDNA members, are all genetically linked to form the Genetic Community Early Settlers of Northern Arkansas & Middle Tennessee.

.....Settlers of the Ozarks & Middle Tennessee--You and 114 of your DNA matches, along with 9,988 other AncestryDNA members, are all genetically linked to form the Genetic Community Settlers of the Ozarks & Middle Tennessee.

Early Settlers of Tennessee & the Deep South--You and 709 of your DNA matches, along with 214,588 other AncestryDNA members, are all genetically linked to form the Genetic Community Early Settlers of Tennessee & the Deep South.

















My Daughter
Early Settlers of Tennessee & the Deep South
Early Settlers of Northern Arkansas & Middle Tennessee
Early Settlers of Georgia & Florida


Mom
Early Settlers of Northern Arkansas & Middle Tennessee
....Settlers of the Ozarks & Middle Tennessee
Settlers of East Tennessee & the Blue Ridge Mountains
Settlers of Missouri Ozarks & East Tennessee




















My sister(full sibling)
Early Settlers of Northern Arkansas & Middle Tennessee
Settlers of Western Tennessee, Arkansas & Northeast Texas
.....Early Settlers of Tennessee & the Deep South
Early Settlers of Northern Alabama


















Clicking on one of your Genetic Communities takes you to a Origins page which includes a timeline and a more close-up view of the area it covers.



From there selecting CONNECTION loads a page which has a list of your matches and the Top Surnames found in that community.


I'm sure this feature will be helpful to many people especially those who don't already know much about their ancestry and those who immigrated later on.  Keep in mind that I'm writing this from the perspective of someone using the US version of Ancestry with colonial American roots on both sides of the family.  The experience will be different for each person.  I feel like the communities are too broad right now to be of any significant help to me.  I'm hoping that will change as time goes on and we will be able to look at a more detailed group.  While I do like to see the Associated last names, I think a better option would have been to link those names to a search of your matches from that genetic community.  When I clicked on a name that was what I expected(Yes I didn't read the text up above the names before clicking).  Still, a great feature and I'm sure it will bring additional interest in researching both genetic and traditional ancestry.

Shared Ancestor Hints are just that--Hints


I was extremely happy to get 14 new 4th cousins or closer matches on my AncestryDNA results overnight.  I wish people understood the importance of uploading to GEDmatch. Too many treat the circles or the DNA Hints as facts.  To them it is unnecessary to upload their raw data atDNA results to GEDmatch because Ancestry has told them the connection. Sure,  if you don't want to prove your research, go ahead and believe that!  Ancestry gives you hints and clues,  It is on you to investigate and research those.

I have the perfect example among my matches.  This match is kin to me on my Mom's side thru the Luna line at my 4th Great Grandparents.  She is not DNA kin to me or my Mother but she shows as DNA kin to my daughter and the Shared Ancestor Hint is my 4th Great Grandparents(my daughter's 5th Great Grandparents)  Clicking on the "i" shows that my daughter and this match have a shared estimated atDNA of 6.6 centiMorgans(cMs) shared across 1 DNA segment.


Ancestry has done a better job on their wording on the Shared Ancestor Hints than they did when they first appeared.  [If you want to learn more about hints & shared records watch Ancestry's Crista Cowan and her presentation, "Don't be a Searcher, be a Researcher" from RootsTech 2017.


What we should hear  "You have a 6th cousin through the Luna line of your maternal Grandmother with whom you share a 6.6 cM  portion of DNA across 1 segment.  It is possible that it may be through that Luna line. You need to investigate further"

Instead many people feel that they don't need to investigate further and take that info at face value whether it is through lack of understanding, laziness or just not really carrying to know the truth. I'm not talking about those that just tested to learn ethnicity and don't care to do more. I am fine with that.

Thankfully this match agreed to upload to GEDmatch.  Since both of my daughter's Paternal Grandparents have tested I was able to tell that the connection was through my daughter's Paternal Grandmother's lines.  I was also able to take it back a step further in finding where to look as my daughter's PGM's Mother(my daughter's Great Grandmother) had also tested.

The match amount at GEDmatch to:
Daughter:  11.3 cMs on 1 segment
Her  PGM:  12.4 cMs on 1 segment
Her PGM's Mom 12.6 cMs on 1 segment

I should also mention that while my Daughter tested at AncestryDNA, her PGM tested at 23&me and her Great Grandmother tested at FTDNA.  We can compare all of these test at GEDmatch.

I did run the One to One for this match against my results and my Moms and she didn't have any measurable DNA match with us.
