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
Moorish architecture is the articulated Islamic architecture of northern Africa and parts of Spain and Portugal, where the Moors were dominant between 711 and 1492. The best surviving examples of this architectural tradition are the Mosque–Cathedral of Córdoba and the Alhambra in Granada (mainly 1338–1390), as well as the Giralda in Seville (1184). Other notable examples include the ruined palace city of Medina Azahara (936–1010) and the Mosque of Cristo de la Luz, now a church, in Toledo, the Aljafería in Zaragoza and baths at for example Ronda and Alhama de Granada.
