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.

It is important to understand that the term "Moor" is not the term for a specific ethnic group, but rather the term used by the European Christians, in reference to the Arab and Berber populations that hailed from North Africa in the medieval era and soon took control of Malta, Sardinia, Spain, southern France, Portugal, southern Italy, and Sicily. Another term that was used in reference to the Arabs and Berbers at this time was "Saracen." This was largely used to refer to the peoples of the entire Arab Islamic empire, mostly used by Italians and Europeans to the north. The term largely fell out of use post- Middle Ages.
