I am trying to find my dad's old medical records from 1963. I know that Allegheny General Hospital has taken the records for Bellevue Hospital but they can't find his records. He was in that hospital for 6 weeks before he died and also before that for surgery. His doctors were Dr. Bernard from Emsworth and Dr. Allison but they are both long gone. Does anyone have any idea how I can get the records for my mother? Mary Lou
