aloha! came across your website & wanted to drop a line. my grandfather's name (and uncle) was petka. his name was albert and he was born in mckeesport, Penn and moved to chicago where my dad was born in 1920. my dad changed his name to petke in the 1930's due to some problem with his ssn info (or so he said). anyway, my dad had a brother named ben and a sister named irene.
