African DNA Cousins reported for people across the Diaspora

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 individuals with 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.

How to find those elusive African DNA matches on Ancestry

Zoom in Gambia

Ethnicity summary of my most likely Gambian DNA match on Ancestry.com

Gambia Match

***

A couple of months ago i found my very first mainland West African DNA cousin on Ancestry.com. Judging from his name and ethnicity preview he is a Mandinga from Gambia. I was exhilarated!  I had never been able to find a mainland West African match before. Even when i took my first DNA test with 23andme already in 2010! In other words I had to wait seven years for it! Inspite that i haven’t had any meaningful contact yet this genetic connection is still very valuable to me. As I am of Cape Verdean descent this finding seems very appropriate and in line with my primary Upper Guinean roots (see Top 20 Ethnic Roots for Cape Verdeans).

Many people seeking to trace back their African ancestors are very eager to be connected to a specific place and person within Africa. They hope to achieve this by finding a DNA match from the continent. But just like me they are having a hard time to do so. In the beginning this was mostly because only very few Africans were included in the customer databases of companies such as 23andme or Ancestry.com. Fortunately this has been changing lately because a quickly growing number of Africans or rather African migrants and their children are taking a DNA test. This increases the likelyhood of receiving African DNA matches. However many people still find it difficult and/or tedious to sort out their DNA matches. In this blog post i will therefore describe a method which enables a systematic, comprehensive and time saving detection of your “100% African” DNA matches on Ancestry.com.

“Cameroon/Congo” = moreso Angola/Congo for Diasporans?

I have created a new page featuring the AncestryDNA results for persons from Central Africa as well as Southern Africa. I will create a new section for West Africa shortly. Despite the minimal number of results i have collected sofar i also provide some statistical data, background information and relevant context.

AncestryDNA results from Cameroon & Congo contrasted with AncestryDNA results from across the Diaspora showing maximum scores of socalled “Cameroon/Congo”.

In addition i also discuss the implications these results might have for Afro-Diasporans. Generally speaking when it comes to tracing back the main strains of regional African lineage for Afro-Diasporans in the Americas undoubtedly results from the Democratic Republic of Congo as well as Angola will be most relevant, given historical plausibility and cultural retention. Although also Cameroon, Mozambique, Madagascar and directly surrounding countries, such as Zambia, Gabon, Congo Brazzaville and Malawi are not to be overlooked. As a general disclaimer of course in individual cases several ancestral scenarios might apply. And with corroborating evidence a Cameroonian or rather a Bight of Biafra connection might still be demonstrated to be valid for many persons. Even when based on the discussion below Congolese & Angolan ancestry seems much more likely on average.

45 Haitian AncestryDNA Results

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.

AncestryDNA Results Across the Diaspora

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.”

Fictional Family Tree incl. African Born Ancestors

familytree

Fair warning in advance: this whole post is just meant as an eloborate thought experiment. Let’s imagine that somehow for a fictional Afro-Diasporan we ARE able to trace back and identify the ethnic origins of ALL of his African born ancestors for the last 7 generations. How would that look like on paper?  And what does it imply for anyone in the real world who’s faced with a missing paper trail in most cases and usually in need of tons of luck and perseverance to even identify 1 single African ancestor?
