I am searching for information about Mary Briggs. After my great grandmother Lulu Zoe Denniston Grimes died at the age of 26, One of her son's, my grandfather, went to live with Mary and one of her grown sons. The other two son's stayed with their grandparents T.G. and Amanda Denniston. My grandfathers name was Clarence Earl Grimes. I would like to know what relation Mary was to my grandfather. Mary lived on a farm, she was born in New York in 1844, she had 7 children. Her husband's name may have been Henry. I would greatly appreciate any information.
