“Benin/Togo” Region

Is “Benin/Togo” really pinpointing origins from within Benin’s borders?

One of the most surprising outcomes of my survey of AncestryDNA results across the Afro-Diaspora has been the higher than expected average scores for “Benin/Togo” seen for African Americans and also Anglo-Caribbeans, especially Jamaicans. It is surprising because even given individual variation and many possibilities of “real” Beninese ancestry to some (minor) degree, documented Trans Atlantic slave trade data does not seem to support such a consistently high average level of “Benin/Togo” for the Anglo-Caribbean and even less so for the USA. We can see this clearly in the second chart above generated from the Slave Voyages Database. If we compare the percentages of the Bight of Benin with the calculated shares of total African for “Benin/Togo” according to AncestryDNA there are major discrepancies especially for Jamaica and the USA (Louisiana being a notable exception but not really representative for the rest of the States). It’s intriguing to think about what might possibly be causing this outcome. The following three scenario’s i will mention can perhaps provide partial explanations for the unexpectedly high “Benin/Togo” percentages being reported but as a fair warning in advance they are also speculative!

The slave voyage data from Barbados indicates that especially in earlier timeperiods (1600’s and early 1700’s) there was indeed a significant inflow of captives from Benin arriving in the West Indies. And possibly by way of Inter-Colonial Slave Trade these captives were also partially brought over to Jamaica when its plantation economy was being set up in the late 1600’s as well as to the US. According to a latest study (O’Malley, 2014) this Inter-Colonial Slave Trade route would amount to about 15% of overall slave importations for the Thirteen Colonies, being more pronounced for some states than others (see last chart).

Even inspite of the prevailing brutal living conditions in the Caribbean – causing negative reproduction rates in general – it might possibly be that cumulative founder effects were set in motion by those people who did manage to survive the ordeal and passed on their genes to the first generations of locally born slaves in the Caribbean as well as to some degree in the USA. So it would seem in this case the inherited “Benin/Togo” markers could be signalling genuine Beninese ancestry, especially from the Fon and other Gbe speaking groups who would have had a relatively larger presence during these earlier timeperiods.

Another undocumented source of genuine Beninese origins i can think of is that despite being shipped away from the socalled “Gold Coast” (and also counted as such in the slave trade data above) a higher than expected number of these captives (often just assumed to be Akan speakers) might actually originally have been from the Benin/Togo area. Which is to say that the proportion of Gbe speaking people among Gold Coast captives might have been underestimated. Only ending up in the European slave ports along the Gold Coast instead of the Bight of Benin because of coastal shipping or overland routes.

A third possibility being that the illegal slave trade taking place after 1807/1808 and also involving the Bight of Benin (e.g. the Clotilde voyage in 1859) was greater than imagined sofar. However given the very low reported rate of African born slaves in the USA throughout the 1800’s and the documented early creolization of American slaves in general this option seems least likely to offer an overall explanation for the high averages of reported “Benin/Togo”, although in selected individual cases it could very well be.

Benin’s largest ethnic group is the Fon (39%), followed by the Adja (15%), Yoruba (12%) and Bariba (9%). Togo’s largest ethnic groups are the Ewe (21%), Kabye (12%), Mina (3.2%) and Kotokoli (3.2%). Benin has more ethnic ties to its neighbor Nigeria; Togo has more links to Ghana. These ethnic ties are the result of long-standing kingdoms that flourished before European colonists created new borders.” (Ancestry.com)

Many people in Togo and Benin speak one of about 20 related Gbe languages. Linguistic evidence indicates that most of the Gbe people came from the east in several migrations between the 10th and 15th centuries. The Gbe were pushed westward during a series of wars with the Yoruba people of Nigeria, then settled in Tado on the Mono River (in present-day Togo).” (Ancestry.com)

Ninety-six single nucleotide polymorphisms (SNPs) and seventeen short tandem repeat (STRs) were investigated on the Y-chromosome of 288 unrelated healthy individuals from populations in Benin (Bariba, Yoruba, and Fon) and the Ivory Coast (Ahizi and Yacouba). We performed a multidimensional scaling analysis based on FST and RST genetic distances using a large extensive database of sub-Saharan African populations. There is more genetic homogeneity in Ivory Coast populations compared with populations from Benin. ” (Genetic population study of Y-chromosome markers in Benin and Ivory Coast ethnic groups“, 2015)

____________________

Given the fact that AncestryDNA tested Africans themselves also show regionally mixed testresults (usually only neighbouring and overlapping regions, see also this pageit is wise to be careful in drawing premature conclusions and also consider other ancestral options. In the screenshots above we can see that prudence is also called for by Ancestry.com itself. Especially the apparent existence of Ghanaian reference panel candidates scoring over 90% “Benin/Togo” gives food for thought. Ancestry.com was careful to remove this single sample for good reasons however it’s a very clear indication of the overlap between Ghanaian and Beninese samples utilized by AncestryDNA as can be seen in the first screenshot above. In this very insightful plot it is shown that the “Benin/Togo” and “Ivory Coast/Ghana” regions cluster the closest from all other African regions on AncestryDNA. And furthermore the samples from Benin/Togo and Ghana/Ivory Coast are the only ones that seem to overlap to some degree. Suggesting that they’re genetically very close indeed and there might be some incorrect assignment between the two as it would be impossible to make any distinction in some cases.

There are several possible reasons why this should be so (see also more detailed discussion on the AncestryDNA Regions page). But it’s probably mostly due to widespread ancient shared ancestry across Ghana, Togo and Benin, extending into southern Nigeria a putative home land of many Kwa/Gbe speaking groups, as well as being correlated with ethnic background in Ghana. Especially the non-Akan groups (more than half of the total population of Ghana) and particularly the Ewe (who also live in Togo and are Gbe speakers just like many ethnic groups from Benin) possibly possessing a higher degree of “Benin/Togo” markers. Counterintuitive perhaps at first but still very insightful if you are aware of the relevant context. As can be verified from the one single AncestryDNA result i have obtained sofar for a quite likely Ewe person below. However i suppose due to widespread ethnic intermarriage “Benin/Togo” DNA markers could probably also show up for Akan speakers themselves.

Again the country name labeling of the AncestryDNA regions should therefore not be taken at face value. “Benin/Togo” might signify different and wideranging ethnical roots also outside of Benin’s borders depending on your own nationality. For Haitians (whose results do show the highest average score among Afro-Diasporeans for this region as expected, see very first chart above) and Brazilians this category is indeed very likely to be derived from the Fon, Adja or Yoruba. Given their confirmed and well documented ancestral/cultural connections to Benin and Yorubaland. For African Americans and Anglo-Caribbeans “Benin/Togo” is perhaps more likely indicative of Ewe or other types of non-Akan ancestry from Ghana/Togo.

Additionally also Nigerians (even Igbo’s!) might have carried over some ancient “Benin/Togo” component into the genepool of African Americans, Jamaicans & other Anglo-Caribbeans.  Even more so than for Ghanaians showing “Benin/Togo” markers in their genome the “Benin/Togo” labeling is misleading for Nigerians as it misrepresents the most likely east to west direction of geneflow for these DNA markers. It is perhaps best to consider this a component “X”, originating within Nigeria but nowadays seen most frequently (but not exclusively!) among people from Benin/Togo because of ancient migrations, shared origins and founding effects.

We can verify this by reviewing the two AncestryDNA results shown below for persons of confirmed fully Igbo and Yoruba ancestry. As expected because of geographical proximity the Yoruba person shows a greater degree of “Benin/Togo” than the Igbo person, but for both it is very substantial. They are of course only individual results (see the very first chart for a group average calculated by myself and this graph for the samples used by Ancestry.com) but in theory any Yoruba or Igbo ancestor having a similar genetic profile could have passed on “Benin/Togo” markers to their American-born descendants. For Jamaicans the Yoruba option is likely to be more relevant than it is for African Americans because of the additional arrival of socalled “Nago” contract labourers after the Abolition of slavery. But for both i suppose at least a minor degree of socalled “Benin/Togo” could very well also have found its way in their AncestryDNA results by way of Igbo or Biafran ancestry.

Each case to be judged on its own merits naturally and depending also on any possible additional clues. All things being the same i suppose for people with “Benin/Togo” reported as number 1 main region a Biafran explanation might be least likely and other more plausible scenario’s should be explored. However each of the above described ethnic options or also a combination to any degree could still be possible in individual cases 😉 Right now there’s just no way of making the distinction. Perhaps with an upcoming update there will be more clarity. But even so a perfect measure of “genuine” Beninese ancestry might never truly be possible due to artificial manmade borders and a high degree of genetic similarity between neighbouring ethnic groups. In the end all of these ancestral clusters and regions are afterall constructs much like the very concept of “ethnicity” itself.

    • I just wanted to point out too that I manage Nigerian kits (1 Igbo, 2 Yoruba & 1 Efik) via AncestryDNA and Benin/Togo is the top regional cluster. among two of them, I also think that a sizable degree of Benin/Togo appearing among African Americans is connected to Ewe genetics, though not the only of course. I think it would be great if we (if you haven’t already started) create a catalog of ethnic groups that map to AncestryDNA’s regional clusters. It could very likely help to predict better ancestry regional affiliations more precisely (semi-precisely). For example, we know that southern Nigerians (East-West) almost certainly map to the Nigeria and Benin/Togo regional clusters. As well we know that Fula and Cape Verdeans map to Senegal and Mali. What if we build a large ethnic-regional cluster mapping directory? It’s something to consider, right?

  1. I am jamaican and took the ancestry DNA Test. I am a descendent of Mooretown, the Maroon community in Portland, easter Jamaica near Port antonio. I know that my great great grandmother/grandfather spoke Twi or a version of it. Yet when I did my test, i was found to have only 10% ghana/ivory coast and 40% benin/togo. I have met many Ghanaians in American and they have ALL told me that I look like them! I have also met people from Bein/Togo, and I have never been told that I have any resembles to them. One person have told me that the Haitian people in New York City resembles them. I have looked at pictures of both sets of people, and generally I see no resembles between us Jamaicans and people from Benin/Togo, but its quite obvious as a Jamaican that we resemble the people from Ghana. I know that looks is not all to determining genetic relationships, but i sense that ancestry.com is completely off withs assignment of DNA to people of Ghana-Ivory/Benin-Togo. They seem to have a hard time distinguishing the two, and this may be the only reason for the discrepancies listed above!

  2. Hi I was wondering if you could possibly assist me. I’m mixed race 51% African the breakdown is 32% Nigerian, 13% Benin/Togo, 4% Mali, 1% each s.africa & Ghana. I understand Benin/Togo can be considered both Nigeria or Ghana. I’m finding it a little confusing. How would you read these results? Thank you in advance

    • Without any additional context i cannot tell you that much beyond speculation. However it might be telling that your “Ivory Coast/Ghana” score is only 1%. It *might* be indicative that your “Benin/Togo”% is more so related to your predominant Nigeria amount. If you like to zoom into closer detail of your possible ethnic lineage, i recommend you start searching for African DNA matches. I have recently blogged about it:

  3. I’m African American. Benin/Togo 46% Cameroon/Congo 17%. Africa Southeastern Bantu 11%
    Senegal 7%. Mali 6%. African South-Central hunter-Gathers 2%. Ivory Coast/Ghana 2% and
    Nigeria less than 1%.

    After reading a lot of information about Nigeria and Ghana’s relationship to the markers of Benin/Togo.
    I have virtually none of Ghana or Nigeria DNA What do you make of this? Does this mean I have genuine Benin/Togo DNA? How can I have such a high Benin/Togo and no Nigeria or Ghana. Total let down I have not an ounce of Ghana and even less Nigeria. I’m shocked I’m even 92% African. I’m just too thrilled‼️But confused.

    • Hi Felicia, the odds of “Benin/Togo” being genuine are determined first of all by your background i would say. You would have to study the documented ethnic/regional origins of enslaved Africans being brought to the states where your earliest known African American ancestors were from. However from what i’ve read there’s very few places where genuine Benin lineage (Fon/Gbe) would ever have been truly predominant in the USA (they were present in significant numbers in several states though). To be frank i think for a greater majority of African Americans “Benin/Togo” will rather suggest Ewe lineage from eastern Ghana or southern Nigerian lineage. Or also a combination of both and in some cases also some genuine connection to Benin and/or Togo thrown in the mix as well. In your case 46% of your DNA could very well trace back to several dozens of individual ancestors who were born in West Africa and relocated to the Americas. You can almost be certain they would not have been from just one place or just one ethnic group. Although in all likelyhood still closely interrelated and geographically nearby.

      In order to confirm atleast one single family line it is very useful to search for African matches. I highly recommend that you start searching for them if you haven’t done so already. You are very likely to have some Nigerian or Ghanaian DNA matches inspite of low amounts for these regions in your AncestryDNA results. I have looked into the DNA matches for over 30 African Americans and practically all of them had matches from those countries. Matches from either Benin or Togo are a rarity, probably first of all because of a lack of genuine ancestral ties but also because migrants from those countries to the US or the UK are much fewer in number than Nigerians or Ghanaians who are therefore a bit overrepresented in AncestryDNA’s customer database.

  4. FonteFelipe – think this analysis is fascinating. I’m African American and found that I have 22% out of 66% African from Benin/Togo as well as 14% Nigeria, 13% Cameroon Congo and 6% Ivory Coast/Ghana. I read your hypothesis on the Benin/Togo markers coming from the Ewe people and found an article about the Ewe’s in Ghana with a picture of tribal elders at a festival and one of them looked nearly identical to my maternal grandfather and his son my maternal uncle. The resemblance was more than striking, I’d love to share the pictures with you at some point. Based on that I’m fairly well convinced that I’m descended from the Ewe and despite Ghana being a lower percentage according to Ancestry. I’d be interested in your thoughts…I’ll follow the steps to share my results for your insight.

    • Hi Chris thanks a lot for your comment! Finding resemblances with actual African persons is always fascinating. It’s something that i’ve been intrigued by for a long time actually. And i do think something is to be learnt from it. But more so going by generalized trends and not so much on a person to person basis as the individual variation among Africans themselves will be too great. As they say phenotype does not always follow genotype (although it usually is correlated even when not perfectly so). And from that perspective appearances can indeed just be skindeep and even misleading.

      You might still indeed have Ewe lineage however i like to underline that socalled “Benin/Togo” is not an exclusive marker for any given ethnic group. It could be suggestive of many different ethnic origins from eastern Ghana into southern Nigeria, while possibly also some ethnic groups further west such as the Gur speaking people in Burkina Faso and northern Ivory Coast might score substantial amounts for this region as well. I intend to do an update on this page eventually based on enhanced insights from my ongoing survey.

      I had a look at your DNA matches and i filtered out the quite likely African ones according to my tutorial (see this link). The outcome was very interesting and somewhat surprising. I would like to stress that these matches should be interpreted carefully. While providing very valuable insights and more detailed specifics on your African roots. They are at the same time only informative of single family lines and not your entire DNA or ancestry. The odds of being matched are also dependent on the number and specific origins of DNA tested Africans within Ancestry’s customer database.

      Having said all that i managed to single out atleast 12 African matches for you ( i will send the details by PM). I am not entirely sure of their background but their names are usually quite indicative. One of them is most likely from Ghana, not sure if Ewe. Another one is possibly from Nigeria. Two matches are quite likely from either Central or East AFrica. But the greatest number of your AFrican matches seem to be from the Upper Guinea region, that is Senegambia, Sierra Leone/Guinea and Mali! From what i’ve seen sofar this pattern is quite exceptional for African Americans. They do regularly have Upper Guinean matches but compared to their Nigerian or Ghanaian matches the number is almost always fewer. But in your case (sofar 😉 ) it’s the other way around. Even when combined your “Senegal” and “Mali” scores are only 6% out of 66%. Naturally as more and more Africans will do the AncestryDNA test you might eventually also receive more Ghanaian and Nigerian matches. Still a very useful outcome as it illustrates how proportionally speaking your individual DNA matches will not always correspond with your entire autosomal DNA makeup.
