I read your post with great interest regarding the changing of your daughter's blood type. I was typed in my youth as AB+ and later retyped as O+. I thought this was really odd, too. I've never received blood to my knowledge, although I have had surgery. Of course they could both be mistyping incidents. I, too, am Celtic-- Scots-Irish, Cherokee Indian and French. If the ancient European burial site information is correct about Celtic warrior feet then I display that genetic make-up (long middle toes are believed to be genetic markers of Celtic ancestors). The UFO researchers of such genetic combinations have often stated that an American Indian and Celtic combination appears to be desirable for human hybridization programs (by whom? another good question--ETs or humans?), according to the best research I've been able to establish so far. But even stranger is the rh- factor. It plays into the same scenario and has generated some interest in the community. No one to my knowledge is sure why rh- blood appears desirable. No theory out there postulates why negative blood types would be so. Maybe a DNA expert might be able to theorize a reason but they have not joined in the conversation. both types of Contactees, negative blood types and Celtic combination genetics tell some strange tells.
