My Grandfather's name was Alfred Sather and he was an only child but his father (my great-grandfather), I think his name was Carl, had many brothers and sisters. I think he had one brother and 3 sisters not sure though. Grandfather grew up north of Minn., MN. I do know that the woman Great-Grandfather married had the maiden name of Hill. I am sorry that it is very little to go on but I am wondering if anyone can help.
