Given that children on both sides of Hamilton had Mattie as their mother, and given the 1910 Census which shows 5 children for her, 3 Beeson children and 2 Collins children, I think it is certain that Mattie Brown Collins Beeson is Hamilton's mother..
The way to confirm this would be to get a copy of Hamilton's 24 Jan 1976 San Diego County, California Death Certificate.(State of California. California Death Index, 1940-1997. Sacramento, CA, USA: State of California Department of Health Services, Center for Health Statistics. Ancestry.com. California, Death Index, 1940-1997 [database on-line].
