Many individuals who see that their ethnicity estimate from a DNA check is method off, suppose that they can’t belief the opposite findings from that testing firm. That may be a false assumption.
If you find yourself proven individuals who share DNA with you, aka DNA matches, they are surely your family members, though some may be fairly distant. What the connection really is might not be predicted very precisely, as many relationships share comparable quantities of DNA. Examples of which might be a grandparent and an aunt or a 2nd cousin and a primary cousin as soon as eliminated. Thus you might be often proven a variety of potential relationships. Figuring it out from shared matches and timber may be a number of enjoyable!
Lately “Gail,” a DNA match to my South African third cousin Sharon, contacted me. The one widespread ethnicity that was proven for them at their testing firm was Ashkenazi Jewish. Thus she was assuming that their widespread ancestors have been Jewish.
Nevertheless the issue is that Gail inherited her 2.7% Jewish from her mom who doesn’t match Sharon. Gail has no Jewish on her father’s facet that she is aware of of. My cousin’s 28% Jewish is from her maternal grandmother. That’s the line the place Sharon matches me (click on right here for that story). Gail doesn’t match another of my many many examined members of the family on that line.
One of many points that folks of Northern European descent have is that our ancestors intermingled fairly a bit. Which means that your Scandinavian might be my English and I believe that’s the case right here. One other downside is that not like relative matching, predicting your organic ancestry out of your DNA is much from an correct science (click on right here for my most up-to-date article of many on that topic)
Extra correct than ethnicity are the shared family members. When trying on the matches Sharon and Gail share, I discovered a set of widespread ancestors amongst them which might be from a non Jewish South African line.

I additionally discovered a relative who shares the identical giant section of DNA that triangulates with Gail and Sharon. If you share a big section match amongst 3 folks, the expectation is that it’s from a typical ancestor.
Curiously this match shares Scandinavian with Gail as proven beneath.
A number of testing corporations like 23andme and Ancestry now present ethnicity damaged down by chromosome. MyHeritage doesn’t do that but. After I regarded on the ethnicity of the bigger section Sharon and Gail share at GEDmatch, it was clearly North European. The smaller section was much less clear and might be Jewish or false.
The lesson right here is to not soar to conclusions based mostly on shared bio-ancestry. Have a look at the opposite proof similar to shared family members and the precise section(s).
