This Sam is old enough to be father of your William Henry, but may have had a "previous" wife.Both Samuel G. and William, with their families are on the 1900 census Union Co, KY.I would follow up on this Samuel G. Gray, see if he left any land or a probate record, does William show up as an heir?But, Samuel may have left everything to his second and younger family, since his older children would be out on their own, by then.
BTW, 1880, 1900, 1920 & 1920 censuses shows William born in KY.
