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.

When the Romans landed in Africa, the Moors maintained a neutral stance, but after the quick Roman victories, most of their tribes pledged loyalty to the Empire. The most significant tribes were the Leuathae in Tripolitania, and the Frexi in Byzacena. The Frexi and their allies were led by Antalas, while other tribes in the area followed Cutzinas. The Aurasii (the tribes of the Aurès Mountains) in Numidia were ruled by Iaudas, and the Mauretanian Moors were led by Mastigas and Masuna.
