I am looking for my great grandfather Thomas Buckland Hamm. My Dad's name is Marvin Dale Hamm born in 1940, My grandfather Leland Albert Hamm born around 1896 in either Texas or Indian Territory in Oklahoma. Since I can't look at the 1890 census I am not sure where my great grandfather or his wife Sally Gross was at the time. In 1900 I find my grandfather, sister Ann, and brother living with Sally and a stepfather. Any help would be greatly appreciate.
