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.
Māori people
The Māori (; ) are the indigenous Polynesian people of New Zealand. Māori originated with settlers from eastern Polynesia, who arrived in New Zealand in several waves of canoe voyages some time between 1250 and 1300. Over several centuries in isolation, the Polynesian settlers developed a unique culture, with their own language, a rich mythology, and distinctive crafts and performing arts. Early Māori formed tribal groups based on eastern Polynesian social customs and organisation. Horticulture flourished using plants they introduced; later, a prominent warrior culture emerged.
