DNA matches reported by 23andme for 75 Africans

Wishing to share the vibranium 😉 I have created a new page featuring the DNA matches reported by 23andme for 75 Africansall across the continent. These results were collected by me in 2015 when 23andme’s Countries of Ancestry (CoA) tool was still available.

My survey results might have limitations in several regards but I do believe these African CoA results can still reveal relevant tendencies in DNA matching. I intend to compare these preliminary matching patterns eventually with my more recent findings for Africans who tested on Ancestry. I provide detailed background info as well as screenshots of the individual results on this page:

“Benin/Togo” also describes DNA from Ghana & Nigeria

I have created a new page featuring the AncestryDNA results for West Africans from the following countries: Liberia, Ivory Coast, Burkina Faso, Ghana, Togo & Benin. I will create a new section for the remaining part of West Africa (Upper Guinea) shortly. The number of results I have collected so far might be minimal but already my survey findings turn out to be quite insightful. I also provide some statistical data, analysis and relevant context. Follow this link to view the page:

In addition I also discuss the implications these findings might have for Afro-Diasporans in an attempt to improve proper interpretation of their West African regional scores, in particular for “Ivory Coast/Ghana” and “Benin/Togo”. One of these implications I will also discuss in greater detail in this blog post:

“Benin/Togo” is also predictive of Ghanaian & Nigerian DNA

The so-called “Benin/Togo” region seems to be quite predictive of Beninese origins (based on two results). However in addition ancestry from eastern Ghana and southern Nigeria might also be described by this region. You will need to perform your own follow-up research in order to find out more specifics.

“Ivory Coast/Ghana” also describes Liberian DNA

“Ivory Coast/Ghana” is also predictive of Liberian & Sierra Leonean DNA

The socalled “Ivory Coast/Ghana” region is indeed quite predictive of both Ghanaian and Ivorian origins. However in addition ancestry from Liberia and to a lesser degree (southern) Sierra Leone might also be described by this region. You will need to perform your own follow-up research in order to find out more specifics.

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.

Diaspora Overview

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.

Locating Afro-Diasporan haplogroups within Africa

Dissecting... (Tabel S6, country breakdown)a

Dissecting the Within-Africa Ancestry of Populations of African Descent in the Americas (Stefflova et al., 2011)

Limitations of our study

Our database and analyses have several limitations. First, there remains limited data from W/WC Africa, where the published literature does not cover Ivory and Gold Coasts. Thus, the analysis of genotype data is limited by the available published data.”  […] 

“Second, mtDNA is a single locus that can inform us only about group maternal ancestry and needs to be complemented with study of NRY and AIMs. While NRY analysis is complicated by limited resolution and coverage of the published data in Africa as well as Bantu speakers’ migrations.” (Stefflova et al., 2011, p.7)

Ethnic identities of African-born slaves: valid or imposed?

mandinga

Mandinga/Mandingo is undoubtedly one of the best known African ethnonyms in the Afro-Diaspora. Not only in the USA but also in the Hispanic Americas, Brazil and Cape Verde the Mandinga name is still alive in popular imagination but with very different associations it must be noted 😉 Nowadays in Brazil it is used to refer to a distinct capoeira style. In Cape Verde the socalled Mandinga parades are part of carnival celebrations. While in some Hispanic countries (Peru, Puerto Rico) there still exists a popular saying which goes:  “El que no tiene (de) Inga tiene Mandinga“, meaning Lees verder

From African to Creole

1d533c06rgtrt

In the previous post I already discussed the following:

  • Creole” can mean many more things than just referring to Louisiana Creoles.
  • Cape Verdean Creoles/Crioulos are probably the historically oldest self-identified Creole population in the world.
  • In the colonial era the term “Creole” was also used to distinguish between African born slaves and locally born (within the European ruled colonies) slaves.
  • The dating of the socalled Creolization process/transition is fundamental for tracing back African ethnic roots.

I will continue this discussion but in this post I will apply it more generally for Afro-descendants in the Americas and in more detail for African Americans. Lees verder

Shared Upper Guinean roots between Cape Verdeans and Latin Americans

Cape Verde was used by the Portuguese in the 1500’s/1600’s as a midway station for collecting, “seasoning” and reexporting captives born in Upper Guinea to the labour-starved cities, mines and plantations of the Spanish Carribean, Central America, Mexico, Colombia and Peru.  Unlike what you might have expected very few slaves exported via Cape Verde were actually going to Brazil in this particular time period.  Lees verder
