    Do Americans Blacks Have DNA from an Englishman?

    I don't see them on Vahaduo, but if you look at the famous Americans Blacks who have a DNA test, they seem to have some of Europe, mainly Englishman.

    Yes, the average African-American is 20% "white"... their ancestors come from different parts of Europe, including Italy, Iberia, the British Isles, Scandinavia...

    Here are some results for AAs:

    All Afro-Americans have at least some European admixture. What is probably less known, but is something I often encountered, is that Afro-Americans of some US American regions seem have, on a quite regular basis, Native American ancestry too on a low level. Its actually far more common and higher than in Euro-Americans, even in most of those which claim to have Amerindian ancestry.

    The distribution of the admixtures is not random, but concentrates in some states of the USA:

    Going after a study from 2015 Afro-Americans from South Carolina are the most Subsaharan, those from West Virginia among the most European shifted and the ones from the Western states, but also New York and New Jersey have the most Native American admixture. So it seems Afro-Americans which moved West intermixed on a more regular basis with Indians.

    Genome-wide ancestry estimates of African Americans show average proportions of 73.2% African, 24.0% European, and 0.8% Native American ancestry (Table 1). We find systematic differences across states in the US in mean ancestry proportions of self-reported African Americans (Figure 1 and Table S2). On average, the highest levels of African ancestry are found in African Americans living in or born in the South, especially South Carolina and Georgia (Figure 1Aand Table S3). We find lower proportions of African ancestry in the Northeast, the Midwest, the Pacific Northwest, and California. The amount of Native American ancestry estimated for African Americans also varies across states in the US. More than 5% of African Americans are estimated to carry at least 2% Native American ancestry genome-wide (Figures S1 and 1D). African Americans in the West and Southwest on average carry higher levels of Native American ancestry, a trend that is largely driven by individuals with less than 2% Native American ancestry (Figure 1. With a lower threshold of 1% Native American ancestry, we estimate that about 22% of African Americans carry some Native American ancestry (Figure S2).

    Are there examples of "old stock" Afro-Americans (from the USA, no recent African immigrants) with no European admixture at all?

    I wonder whether this ancestry has been confidently identified as Native American as opposed to Eastern Asian & American in general. I have seen mtDNA results for self-identified African-American individuals who belong to clearly Southeast Asian/Austronesian haplogroups (perhaps via Malagasy-related admixture prior to migration to America) as well as others who belong to clearly East Asian (Chinese, Japanese, Korean) haplogroups.

    That's something I considered too, but it seems to be far more exceptional than the Native American admixture. That's not just from scientific studies, but also private testing like 23andme, which consistently proves Native American ancestry in Afro-Americans. However, one doesn't exclude the other. I would have said that in the far West real East Asian admixture could be present or, like you said on a low level from Austronesians or slaves and workers from SEA. Actually, if its real, there should be a pattern.

    What I know defensively is that in ancient times, Austronesian groups (late Pre-Columbian times) have colonized thin coastlines in South America and made trade contacts with the Incas

    I believe a black American pastor called TD Jakes scored 100% SSA on a test. However, that was several years back so his results have likely changed by now.
