I am looking for the maiden name of Margret McCoy, who was married to John Thomas McCoy, who is the son of George Washington McCoy.
According to the 1880 US census John Thomas 28 and Margret 22 lived in Somervell County Texas.
Margret was said to be Native American.
The census says she was in child birth, which would be Sarah Isabel, her other children were Martha 6, Ruben 3, and James 2.
Sarah Isabel was my greatgrandmother.
There may have been a widow named Sarah McCoy 27 living in the same household.
