I through paternal DNA am a match also. My father tested haplogroup B with Family Tree DNA back in 2005. He passed away in 2007, but I compared his ydna against the Gene Tree database and found a 75% match with Koh Bamayoko of Tinkele, Mali.
We do not know anything of this side of the family. Our history starts with my great grandfather born about 1866, we believe in Georgia, USA. The 1900 census stated that he could not speak, read or write English. The last male besides my father is my grandfather Willie Lee Johnson, who was from Rome, Georgia. He married my grandmother Eleanor Gertrude Whitehead, sometime in the 1930's in Rome, Georgia.
If you have any info to add to this please do. I am sure we are related somehow. And with the rare y haplogroup assignment of B that my father was given, it shouldn't be too hard for us to find other ydna ancestors.
B haplogroup is extremely rare in the US...actually it is very rare anywhere outside of Africa.
