I am looking for information on mary j mock. She married monroe tart in 1908 or 1909 in grenada county mississippi. I think she was born around 1895 and died before or about 1930. She is buried in Arkansas. The family says that she or her parents are full blooded native american. I have searched for a grave and i am unable to find it. Can anyone help me locate her grave and find out who her parents were.
