Robert C. Gahagan was the brother of my father Leonard Gahagan. He had two sister, Bessie, and May. Thier mother and father died when they were very young and they were basically raised on farms in Texas by relatives. I have one photo of him, but I think my mother might have more, but would have to check to make sure. My nephew discovered your posting while looking up the name and notified me. My uncle lived next door to my brother in Bakersfield, Calif during his last years. If you have any questions I will try to find the answer or give you a name of someone who might know.
