African-American heritage of presidents of the United States
Calvin Coolidge's mother Victoria Moor was claimed to be of a mixed-race family in Vermont. Vaughn noted that her surname was derived from "Moor", a European term for people of North Africa. He did not note that another meaning of her surname is the landscape feature of moor or bog. People's surnames were often based on such landscape features when surnames became generally adopted in 14th century England. Moor/Moore is a common name in England, Scotland, and Ireland.
Enchanted Moura
Moura is a homonym word with two distinct roots and meanings; one from Celtic *MRVOS, the other from Latin maurus.
The word "moura", (moira, maura) (medieval: mora) feminine of "mouro", is thought to originate from the Celtic *MRVOS and the indo-european "mr-tuos" that originated in Latin the word "mortuus" and in Portuguese/Galician the word morto (dead). Some authors think that the mouras are the deceased.
