This blog post features the AncestryDNA results of 8 persons from 7 different countries. In particular i will list the (most likely) African DNA matches i was able to find for each profile. Using the tutorial i blogged about in my previous blog post:
Naturally this overview is not meant to be representative per se because these persons are in the first place individualswith unique family trees. It is mainly to show the variation across the Afro-Diaspora. Nonetheless I strongly suspect that many patterns to be observed will still be valid as well for other people of the same nationality or ethnic (sub)group.

For this overview I specifically chose people with one single predominant African regional score on AncestryDNA. In order to see how Ancestry’s “Ethnicity Estimate” lines up with predicted African DNA matches. More detailed analysis will follow in this blog post. If you continue reading you will also come across a section featuring inspiring stories of people who were able to reconnect with their African kin through DNA testing.
On the 3rd of October 2015 i published my first preliminary findings based on 15 Haitian AncestryDNA results. Right now, a year later, i have managed to collect a sample group which is three times greater. Consisting of no less than 45 AncestryDNA results of Haitian born or Haitian descended persons! Eventhough this tripled sample size is obviously still limited it will most likely provide a greater insight in the African regional roots for Haitians than was possible last year.
In the remaining part of this blog post i will briefly discuss the main differences with my previous findings from last year. And in addition i will also present some new statistics and background information on the European and Amerindian origins of Haitians as reported by AncestryDNA.
In 2013 AncestryDNA updated their Ethnicity Estimates to include a very detailed breakdown of West African ancestry (see this article). Soon afterwards I started collecting AncestryDNA results in an online spreadsheet in order to conduct a survey of the African regions being reported by AncestryDNA, among both African Americans as well as other Afro-descended nationalities. Attempting to establish how much the AncestryDNA results on an aggregated group level can already (despite limitations of sample size) be correlated with whatever is known about the documented regional African roots for each nationality.
Rumour has it that AncestryDNA will shortly start rolling out a new update of their Ethnicity Estimates. So it seems the time is right to finalize my survey. The sample size for most groups appears to be suffciently robust now to allow a meaningful intercomparison. In the AncestryDNA section of my blog (see the menubar) you can find a detailed summary of my survey findings based on 707 results for 7 nationalities:
Gathering all the results was a great learning experience. It has been a very satisfactory project! My survey report merely represents my personal attempt at identifying generalized, preliminary and indicative patterns on a group level inspite of individual variation. Everyone has a unique family tree of course first of all.
I would like to thank again all my survey participants for sharing their results with me. I am truly grateful for it!
“This frequency of regions being ranked #1 (regions with the highest amount in the African breakdown) is perhaps the best indicator of which distinct African lineages may have been preserved the most among my sample groups.”
