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 ancestors of the Māori arrived from eastern Polynesia during the 13th century, bringing with them Polynesian cultural customs and beliefs. Early European researchers, such as Julius von Haast, a geologist, incorrectly interpreted archaeological remains as belonging to a pre-Māori Paleolithic people; later researchers, notably Percy Smith, magnified such theories into an elaborate scenario with a series of sharply-defined cultural stages which had Māori arriving in a Great Fleet in 1350 and replacing the so-called "moa-hunter" culture with a "classical Māori" culture based on horticulture. The development of Māori material culture has been similarly delineated by the Museum of New Zealand Te Papa Tongarewa into "cultural periods", from the earlier "Ngā Kakano" stage to the later "Te Tipunga" period, before the "Classic" period of Māori history.
