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.
Moors
The languages spoken in the parts of the Iberian Peninsula under Muslim rule were Andalusian Arabic and Mozarabic; they became extinct after the expulsion of the Moriscos, but Arabic language influence on the Spanish language can still be found today. The Muslims were resisted in parts of the Iberian Peninsula in areas of the northwest (such as Asturias, where they were defeated at the battle of Covadonga) and the largely Basque Country in the Pyrenees. Though the number of Moorish colonists was small, many native Iberian inhabitants converted to Islam. By 1000, according to Ronald Segal, some 5,000,000 of Iberia's 7,000,000 inhabitants, most of them descended from indigenous Iberian converts, were Muslim. There were also Sub-Saharan Africans who had been absorbed into al-Andalus to be used as soldiers and slaves. The Berber and Sub-Saharan African soldiers were known as "tangerines" because they were imported through Tangier.
