Do you have information about Gabriel Mark Colver, son of Miriam and John? His daughter, Nancy Beemer Collver, married my great-great-grandfather, Col. Thomas William CLark, in Norfolk County, Ont. His son, Dr. Aaron Clark, lived in Kent County, Michigan, with his wife Lucy Cole Cannon. I was raised in that area. I would like to find Michigan Collvers and any reliable sources of geneaological data. Thank you.
