Pennsylvania Lloyd's

My Lloyd's came from Wales to Pennsylvania to Utah(At least my direct line). Here in the future I will add the siblings of my direct Lloyd line and maybe from there is where we all connect!. I am really having a hard time finding the cemetery and any death notices on a John Roland Lloyd. I know from a biography his son wrote(My 2Great Grandpa Gilbert Lloyd)about his life and the burial of his father when he was a young child! I know he died in Allegheny City(now known as Pittsburg) and he was buried in Rochester, PA but can't find what cemetery. Any and all help would be appreciated!
