I finally located the Byberry hospital records! The PA board of health holds them in Harrisburg. I got a copy of my grandfather's death certificate from them which I've been trying to get for many years. I never knew him as he died when I was 3 years old but now I finally found out when he died and what from. I understand the Norristown hospital records are there too. Lee Kendter
PS: They had blacked out on the certificate why he was in Byberry and what he was being treated for. I did get what I wanted which was his date of death and what killed him.
