“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.

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.”

Louisiana: most African diversity within the United States?

Louisiana Slave Database 1719-1820


Number of slaves with origin specified 29,769
American born (“Creole”) 13,618 (45% of total)
African born 16,099 (54% of total)
African specified ethnically 8,994 (30% of total)


Congo (Central Africa) 2,988 – 33% of African specified
Mandinga (Upper Guinea) 922 – 10% of African specified
Mina (Ghana, Togo, Benin) 628 – 7% of African specified

Congo Square


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).

Ethnic Origins of South Carolina Runaway Slaves

South Carolina Runaway Slaves 1730-1790

Francisco Menendez, a Mandinga runaway slave from South Carolina, became leader of the free black militia at Fort Mose in the Spanish ruled Florida of the 1700’s.


Number of runaway slaves: 2,424
African origins specified: 508


“Angola” (mostly Bakongo) 149 – 29% of African specified
“Gambia” (incl. Mali/Senegal) 61 – 12% of African specified
“Ebo” (Igbo & related ethnic groups) 49 – 10% of African specified

Above summaries are based on the HIGHLY interesting collection of runaway slave advertisements published in American newspapers in the 1700’s:Runaway Slave Advertisements : a Documentary History from the 1730’s to 1790, Volume 3, South Carolina”. This very extensive work was put together by Lathan Windley in 1983 and has been used by many historians ever since.  Besides ethnic/regional origins you can discover many more fascinating details about these advertised runaway slaves if you read the texts closely. The advertisements can be consulted online (after registration) via this great website: The African American Experience.
