“Ivory Coast/Ghana” also describes Liberian DNA

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:

“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.

Documented African Roots of Dominicans

Lemba 4200976_African ethnonyms in Dominican historical sources: 1547-1606

SUMMARY

Estimated number of Africans: 9,648 – 30,000
African origins specified: 79

TOP 3 BREAKDOWN OF AFRICAN BORN SLAVES

Bran” (Guiné Bissau) 15 – 19% of African specified
Zape” (Sierra Leone) 15 – 19% of African specified
Biafara” (Guiné Bissau) 10 – 12% of African specified
Source: Deive (1980, p.239).

Even though this summary is based on a rather small sized dataset (n=79) and reflecting only a limited timespan, there are many indications from other Hispanic American countries to confirm these 3 ethnic groups from Upper Guinea having a significant presence in the Dominican Republic throughout the 1500’s. But they were not the only ones in that particular timeperiod of course and in later decades/centuries the ethnic compostion of Africans within Hispaniola would change constantly with other ethnic origins from Lower Guinea and Central Africa becoming more prevalent.

African origins of Hispanic Caribbeans according to DNA studies

Moreno-Estrada, (2013) - Fig.6A

Reconstructing the Population Genetic History of the Caribbean (Moreno-Estrada et al., 2013)

____________________

We find evidence of two pulses of African migration.The first pulse—which today is reflected by shorter, older ancestry tracts—consists of a genetic component more similar to coastal West African regions involved in early stages of the trans-Atlantic slave trade. The second pulse—reflected by longer, younger tracts—is more similar to present-day West-Central African populations, supporting historical records of later transatlantic deportation.” (Moreno-Estrada et al., 2013, p.1)

“Overall, we found evidence for a differential origin of the African lineages in present day Afro-Caribbean genomes, with shorter (and thus older) ancestry tracts tracing back to Far West Africa (represented by Mandenka and Brong), and longer tracts (and thus younger) tracing back to Central West Africa.”  (Moreno-Estrada et al., 2013, p.11)
