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.
Sri Lankan Moors
The Portuguese named the Muslims in India and Sri Lanka after the Muslim Moors they met in Iberia. The word "Moors" did not exist in Sri Lanka before the arrival of the Portuguese colonists. The term 'Moor' was chosen because of the Islamic faith of these people, and was not a reflection of their origin.
