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.
Molly Maguires
The Molly Maguires were also active in Liverpool, England, where many Irish people settled in the 19th century, and many more passed through Liverpool on their way to the United States or Canada. The Mollies are first mentioned in Liverpool in an article in "The Liverpool Mercury" newspaper on 10 May 1853. The newspaper reported that, "a regular faction fight took place in Marybone amongst the Irish residents in that district. About 200 men and women assembled, who were divided into four parties – the 'Molly Maguires', the 'Kellys', the 'Fitzpatricks' and the 'Murphys' – the greater number of whom were armed with sticks and stones. The three latter sections were opposed to the 'Molly Maguires' and the belligerents were engaged in hot conflict for about half an hour, when the guardians of the peace interfered."
