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.
Moro people
The word "Moro" itself was a exonym which had been used before in the 16th century by Spanish colonisers in reference to a Muslim group of "Moors", which originating from "Mauru", a Latin word that referred to the inhabitants of the ancient Roman province of Mauritania in northwest Africa, which today comprises the modern Muslim states of Algeria, Mauritania and Morocco. With the rise of Mauritania as part of the Muslim Umayyad Caliphate, Muslim armies conquered and ruled much of the Iberian Peninsula from 711 to 1492, for about a total of 781 years in which the term was revived when the Christian-majority Spanish became involved in a war with them and started to call the Muslims as "Moors".
