not sure if this pertains, but i'm also originally from Pittsburgh (b.1961). my grandfather was Alvin Louis Rieck(b.1878-ish) and he married Catherine Bowles (1882-ish-1976). my father Wilbert (1912-1971) married Lois Grab (1927-1982).
I'm actually looking to find information on more family members and to obtain military records for my father from WWII, He was awarded the Purple Heart in Germany and suffered eye damage in an explosion. He apparently helped several English sailors to safety (though this is a memory of a story he told me when I was 5).
