My Grandfather is Arthur Poston, he died in 1968. But from what I have been told, he was a cousin to Tom Poston. I know my grandfather was about 20+ years older then my grandmother she was is second marriage. In his first marriage he had two daughters I think one of their names were Rosilie Poston. My Dad is Arthur and his 2 sisters are Sandra and Carolyn. My grandfather would be about 95-105 years old if still alive.
