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.
Momin Ansari
The Momin of Maharashtra are descended from immigrants from North India. They are split into two groupings, the giyara gaonwala and the bais goanwala. The former are found in Ahmadnagar, while the latter are found near Pune. The Momin were historically a community of weavers, found mainly in the towns and cities of western Maharashtra. They are found mainly in the districts of Pune, Nasik, Ahmednagar, Aurangabad, Jaina, Osmanabad, Dhule, Nagpur, Thane, Kolhapur and Raigarh. The community speak Urdu, but the Momin are bilingual, speaking Marathi as well. They are strictly endogamous, and tend to marry close kin. The Momin are Sunni, and are a fairly orthodox community.
