I watched it with FH last night and it was fascinating. They talked about family histories (documentation versus family stories), did DNA testing, etc.
I was particularly interested in the discussion about black families having oral traditions regarding Native American heritage....I find that many white families have that as well.
FH found it interesting, because he is from Belize and his grandma was 3/4 Indian.
I just thought the show was fascinating. Especially the woman Bliss Broyard, who looks quite white but did a DNA test and it showed 17% West African heritage.There are some cool tabs at the top of the show's webpage!
