I have a record of a James Hamilton Closs.However, his date of birth is July 21, 1891. He was born in Carlow Township, Ontario. I don't have any marriage or descendants information for him. Your query indicates that one of the children had Hamilton for a middle name.If this James H. Closs isn't his father, he may be his grandfather. I have some contacts in that line of the family. If you want my e-mail address, it is Tomlins1@Netcom.ca.
