Hi, Mary. I think there's a very real possibility that the Andrew you're looking for is related to my Thomas, but I'm not sure at this point. There was an Andrew GRAHAM listed in the same household with my Thomas in the 1850 census. His age is given as 40, which would be consistent with your information (the ages given in census records weren't very accurate I've found). This Andrew does not show up in later census records in Thomas' household and I've wondered if he was the same Andrew listed as a tailor in Waukegon in later census records, who is apparently the Andrew you're seeking. Was your Andrew Catholic and was he born in Ireland? Do you have any other information about him?
