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.
Mooro
The Mooro were a Nyungar Indigenous clan who lived in and to the north of Perth, Western Australia, until shortly after European settlement at the Swan River Colony in 1829. Their territory stretched from the Swan River north to the Moore River beyond the northern limits of metropolitan Perth and east to Ellen Brook. Evidence of indigenous occupation of the Swan Coastal Plain extends back more than 40,000 years.
