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 was originally a Moorish settlement and, as with its near neighbour Ojen, survived where others didn't largely because it was away from the coast. After the Reconquest, Moors were not allowed to live near the coast so as to be unable to communicate easily with their kinsmen in nearby North Africa. The moorish influence can still be seen in the town, Acequia del Chorro is a water channel called a Acequia in Spanish, built by the moors that can still be seen here, they are used in the same way as the Levadas in Madeira.
