The Curiosities of Rh-negative Blood


This week I received a comment on this blog:

“Hello..I see I’m not the only one!..I am also a 30 yr old Africa American with Blackfoot ancestors and yes, Rh-negative blood. Have you found any further findings about as to how our blood type came to be?? I admit my life has changed quit a bit also. I’m soo curious NOW!”

I love the enthusiasm that people have regarding their ancestry. I too get excited, even after all these years. There are various speculations about how this blood type came to be. If I had to give a simple answer, I would tell those with Rh-negative blood type that it probably means that you have British ancestors, particularly Scottish or Irish. I don’t think though, that the short answer is good enough. I have spent more time trying to figure out the history (I too am Rh-negative) and have devoted another chapter to it in the newest book in this series, Secret Genealogy V, Black, White and Hamite; Ancestors of Color in Our Family Trees. The paperback version is available here:
