My grandfather was born December 26, 1904 and was adopted by 1910 per census record. Adoptive parents were Charles H. Graham and Mary (Sampson) Graham. He was 53 at the time and she was 61, they never had any biological children. I believe my grandfather was born in Hamilton county, Cincinnati as his adoptive parents lived there per 1900 and 1910 census records. They indicated that his birth mother was born in Kentucky and father was listed as "unknown." Please let me know if you can help or have any suggestions. Thank you!
