Hi Bob,
I'm your cousin. Grandfather Harry died the year before I was born and Grandmother Martha died when I was 6 years old. They were the parents of my father, Norman Lewis Ritter (Bud), who died in 1963. I keep looking for info about Harry but don't know who his parents were.
I still live in PA (King of Prussia now -- from Phila.) and am trying very hard to find any family info as I'm the only one left (that I know of). I'm guessing you're a son of Marion, my aunt? Would love to have more info.
