Where Did I Get That Rh-Negative Blood Factor?


In the early eighth century, a Mohammedan people living in northern Africa, the Moors, took boats and entered Southern Spain. The significant make-up of the Moors was Arabic peoples (meaning they descended from the Arabian Peninsula) and Berbers (from North Africa). The Berbers have a high percentage of Rh-Negative blood in their population, compared to other ethnic groups. Of the many surnames in my family tree, Morris is one of them. It’s quite possible that those with Morris ancestry are descendants of the Moors, who invaded Spain in 711 A.D. The French-Latin for Moor is Maurus and the French Greek is Mauros. Sounds like Morris to me.

If you want another example, an old Webster’s dictionary has the following:

morris, n. More fully morris dance. [From earlier morys, morish, Moorish. See Moor.]

Morris dancing was common in Olde England in pageants and May-day games. The dance could have made its way through Spain and into England. My Morris ancestors are Scots-Irish. I can not speak with them about their oral history. I can though, try to piece together an explanation as to why I have Rh-negative blood.  Suellen Ocean is the author of Secret GenealogyA How-to for Tracing Ancient Jewish Ancestry, Secret Genealogy IIUncovering the Jewish Roots of Our Christian Ancestors and Secret Genealogy III From Jewish Anglo-Saxon Tribes to New France Acadians.
