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.
Moors Sundry Act of 1790
The "Free Moors", Francis, Daniel, Hammond and Samuel petitioned on behalf of themselves and their wives Fatima, Flora, Sarah and Clarinda. They explained how some years ago while fighting in defense of their country, they and their wives were captured and made prisoners of war by an African king. After this a certain Captain Clark had them delivered to him, promising they would be redeemed by the Moroccan ambassador residing in England, and returned to their country. Instead, he transported them to South Carolina, and sold them for slaves. Since then, "by the greatest industry," they purchased freedom from their respective masters. They requested that as free born subjects of a Prince in alliance with the U.S., that they should not be considered subject to a state law (then in force) known as the "negro law". If they be found guilty of any crime or misdemeanor, they would receive a fair trial by lawful jury. The matter was referred to a committee consisting of Justice John Faucheraud Grimké, General Charles Cotesworth Pinckney and Edward Rutledge.
