A gathering place for rh-negative folks…


This blog is becoming a gathering place for those of us with rh-negative blood type. For the last couple of years, many of those responding appear to have African-American ethnicity. I am white, but that doesn’t mean I don’t have any African ancestry. If we go back far enough,we all do.

Besides all of us sharing rh-negative blood type, we share the curiosity of why?

Thanks for sharing your ethnicity with us. It’s fascinating!

Tracing the Origins of Rh-Negative Blood Through Jewish Ancestry


Secret GenealogyI remember the day I saw my family surname on a list of Sephardic Jewish names. The name was listed as being from the ancient Spanish kingdom of Murcia. One letter was different, they used an “i” instead of an “e” but there was no mistaking it, the pronunciation was identical. But what did it mean? Could there be a connection? Of all the countries my patriarchal ancestors hailed from, Spain was not one of them. But it reinforced my suspicions that the family may have been Jewish many generations back.

From the regions that surround her, Spain has attracted people to settle her lands. The Moors controlled Spain for several centuries. When we think of Spaniards we might picture a dark-haired and dark-eyed people with olive skin but blue eyes and fair skin like that of many Germans and Scandinavians represent the Spanish people, as do others. But an old encyclopedia states that “many Murcians… are very dark — a legacy of Moorish ancestors.” Well there you go. When the Moors, with their chieftain Tan’k, overran the Spanish kingdom in 711, there were Berbers among them. Natives of northern Africa, Berbers have a population high in Rh-negative blood.

There are a variety of explanations why someone has Rh-negative blood. Confirming them is not so easy. Our ancestral immigration and invading patterns happened a very long time ago.
