We were told at a family reunion on my birth mother's side that the first ancestors our historians traced us back to were a German slave trader and a minister of African heritage. He had 14 children and we wound up having a humongous family from his tree. It's funny that when I did my DNA test through Ancestry, Germany was not included but besides different parts of Africa I had 10% from Europe (Iberian Peninsula, Great Britain, Finland/N.W. Russia and Ireland. That was probably on my birth mother's father's side. I never met him but was told he looked Caucasian.
Also in one of the Ancestry graphs, India was highlighted, but it listed only trace DNA from southern Asia. I find that interesting because my maternal grandmother told me that her great grandmother (I think it was) did not speak English. She had long black hair and supposedly came over here on a boat with her husband who was Indian. My grandmother wasn't one to make up stories but now I wish I had asked her siblings about it. My first cousin told me our grandmother told him that the great grandmother was Spanish. So perhaps that's the Iberian Peninsula part. One of our family historians made a DVD of our history which was handed out at a reunion I didn't attend but sent to me. I really should find it and finish watching it.
