I agree entirely. I am just about to do a DNA test to see if we can ascertain the ethnology of my g g grandfather who appears to have been African (as seen in photos of his daughter). If he does turn out to be African, or Polynesian (as also has been suggested), then you cannot see it in me or my cousins, though some of their children have hints of something different.So, who knows what else is hiding in our DNA even just a few generations back?
