Looking for info on Joseph Crawley Jr., born in Allentown Pa. in 1926, died in Pleasanton Tx. in 2009. He was a sergeant in the Air Force, and Vietnam vet. He and his wife Natalie Tyson had two children, Joseph Keith Crawley, and Natalie Lynn Crawley. I'm trying to find out who his parents were, and where they came from. Help or info would be appreciated.
