Hello Donna! My name is James G. Nealis and I am one of 6 children of lifelong Chicago resident George J. Nealis. (died 1983) George was an only child. George's father's name was Henry, and he too lived in Chicago, having been a police officer there.I'm afraid the name Dennis Nealis doesn't ring any bells, but I am hardly the family historian. Perhaps I can answer a question or two you may have about my small branch of the Nealis family tree.
