Send a message to the person who requested a photo of the grave monument of Grace Dufty with the following comment:
Benjamin Dufty and Grace Dufty were related to my great grandmother x 3 Sarah Palmer .. uncles and aunts to her ... Sarah Palmer married my great great grandfather on my mother's side John Cole in Devon. I am not sure but according to my research I believe that Benjamin Dufty and Grace Dufty (nee Able) were husband and wife.
