Anyone know him?

Odd request. I had a cousin call from the Midwest to seen if i could track down his uncle thunderbolt (robert gilleo) due to his brother passing away. They had many years apart and not contact. Thunderbolt was a leather craftsman in years past and had a shop "gila river". Now closed. His wife's name is connie.  Men in the shooting world never lose track of a go to guy like thunderbolt.  This is the start of my search to help my cousin dave gilleo. If there is anyone who remembers him or has contact information to give dave would be appreciated. This is a stab in the dark i understand but its seems logical.
