Cannot spell it so I will pronounce it (zam yawn) 1970s Tampa, FL

I am hoping someone here can help me spell the name (zam yawn) for that is the way it is pronounced but I know it is not spelled that way and for years I have been looking for a husband and wife me and my sister called Grandma and Grandpa and their names were Glenn and Pat (zam yawn) and he was a Shriner and they were living in Tampa, Florida in the mid to late 70s and they were very nice people.I have pictures of Glenn that I would like his family to have as I know he passed away in the Smokey Mountains in TN back in the 80s but do not know what happened to his wife but by their ages then till now she would about 108-110 so that is why I'm looking for any family members // first I have to be able to spell the name and thought you might be able to help or give me advice on where to look.

Sincerely,

Terri Allen
