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.
Moors
The term has also been used in Europe in a broader, somewhat derogatory sense to refer to Muslims in general, especially those of Arab or Berber descent, whether living in Spain or North Africa. During the colonial era, the Portuguese introduced the names "Ceylon Moors" and "Indian Moors" in Sri Lanka, and the Bengali Muslims were also called Moors. In the Philippines, the longstanding Muslim community, which predates the arrival of the Spanish, now self-identifies as the "Moro people", an exonym introduced by Spanish colonizers due to their Muslim faith.
