My grandfather, Edward Cassidy, was born October, 1889. His parents were George and Isabelle. I think the Hugh you reference was his brother. However, I don't believe he was a police officer. Edward had three children. My father was one of them. Born in philadelphia in 1922 died 1979. He married my mother and they had five children. We all live in the Philadelphia area.
