“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.

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.”

Gwendolyn Midlo Hall’s remarkable relational database of Louisiana slaves and freedmen (1719-1820), which contains records of over 100,000 enslaved people, includes nearly 9,000 individual Africans by specific ethnicity. The database was first published in 2000 as a CD-ROM, and it is now available free on the Internet. The database is derived largely from notarial and ‘‘succession’’ (probate) records, mostly in French, in which slaves often self-identified their ‘‘nations’’ or ‘‘countries’’. There are 217 different ethnicities recorded, of which 96 have been identified, and a further 121 (comprising 152 individuals) which have not been identified. Of those identified, just 18 ethnicities account for over 96% of the Africans in the Louisiana records. In addition, within that set of 18 principal ‘‘nations,’’ the seven most common (in order, Kongo, Mandingo, Mina, Senegal/Wolof, Igbo, Bamana, Chamba), comprise over three-quarters of the sample. The single most numerous ‘‘nation’’ in the dataset was Africans from Kongo (nearly 3,000 individuals), the vast majority of whom arrived in the late eighteenth and early nineteenth centuries” (Chambers, 2008, pp.335-336).

In the first part of this blogpost i already discussed the main Guinean Bissau origins for Cape Verde according to its 1856 slave census, in this second part i will continue exploring origins outside of Guiné Bissau. When asked about their mainland African roots many Cape Verdeans might assume they only have ancestry coming from Guiné Bissau, this is however not completely true. It’s indeed correct that Guiné Bissau shares a very long and intimate history with Cape Verde. Both countries being ex-Portuguese colonies, united in their independence struggle during the 1970’s. Because of ever increasing English and French encroachment the formal Portuguese influence area within Upper Guinea during the 1600’s was already pretty much confined to modernday Guiné Bissau and Casamance (a region in southern Senegal which only was ceded to the French in 1888 and where a Portuguese-based Creole is still being spoken!).

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)
