Griffith Hatfield and Mary Donley are my 3rd great grandparents. I believe the marriage was recorded incorrectly for Griffith and Mary Donley. Two months before Mary and Griffith were married, Mary's sister Eleanor Donley married a John Haynes. I think when the marriages for the county were recorded the names were mixed up. All of the death certificates I can find for Griffith and Mary's children say Mary's maiden name was Donley. I can't find any previous marriage for Mary to a Haynes which could also be a possibility.
Mary is buried beside Griffith in Fountain Grove Cemetery. The Cemetery records do not have a date for her death or burial. Probably before 1869 as Griffith married again.
