William Bettencourt, if it is the same William, was my Gramps. He passed away in 1979 and was one of the saddest days of my life. He lived in San Francisco and was married to my great grandmother. My maternal grandpa's mother. He raised my grandfather as his own and was one of the most loving men I ever knew. As they grew older, they lived with my grandparents. My grandparents always had family living with them. He loved the Oakland A's and woukd sit and listen to them on his transistor radio. He loved his bread and butter with dinner. He was so kind.
I am pretty darn certain that this is the same Bill Bettencourt.
