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.

The Muslims present in Kerala were distinguished by the Portuguese historians into two groups: Mouros da Terra ("Moors of the Land") and the Mouros da Arabia/Mouros de Meca ("Moors from Arabia/Mecca"). The latter, also known as the "Paradesi Muslims", in fact came from all over the Islamic world. They included Arabs, Persians, Egyptians, Turks, Iraqis, Gujaratis, Khorasanis and Deccanis (and Melakans, Sumatrans, Bengalis). These Muslims were not unsettled navigators but had settled in Kerala. The Malayali (and Tamil Muslim) community as a whole was considerably lower economic standing than the Paradesi Muslims. Up to 16th century, as noticed by the contemporary observers, Muslims settled mainly along the coastal tracts of Kerala (especially in major Kerala ports such as Calicut (Kozhikode), Cannanore (Kannur), Cochin (Kochi) and Quilon (Kollam)). They were traditionally elite merchants who were all part of the brisk foreign trade. Until well into the European period, the Muslims were almost exclusively concentrated in the port cities. Middle Eastern sailors had to rely on lighterage at most of the Kerala ports in the medieval period. This lead them to enter into mutually beneficial relationships with the traditional sea fishermen community. A large majority of fishermen, once low-caste Hindus, in northern Kerala follow Islam.
