I am desperately seeking information about my father-in-laws biological information. I have a son who has a history of cancer and would like to know this information for health purposes. My father-in-law has since pasted away but laid in a nursing home from age 35 to age 62 with a brain tumor. This is what I know about his history: He was born March 20th 1941. His biological mother was a full blood native American woman from Texas. She came to Oklahoma to put him up for adoption. He was in St. Joseph Orphanage in Bethany Oklahoma until he was adopted. Please let me know if you have any information.
