I am interested in the Griffiths. In the 1850 census for Greenup County, John Craycraft is shown with his wife, Charlotta Griffith, 25, and Hugh Craycraft is shown with his wife, Christina Griffith, 23. My guess is that Charlotta and Christina, both born in Tenn., are sisters. I have been told that Charlotta's mother was Nancy Campbell. Can someone tell me more about the Griffiths?
