Congratulations! Let me know if I am interpreting your post correctly. Oral history said that a maternal ancestor in your direct maternal line came from Guinea. Then, you took the mtDNA test from African Ancestry, and of the three matches, one of them was actually with an ethnic group in Guinea?!!! WOW!!! Did you inform the staff at African Ancestry about this? I'd always wondered if someone would verify oral history with African Ancestry's DNA test!!
