Several years ago I was sending off to the Social Security Administration for any Mary Raptos or Mary Chupko (Mary Raptos married Paul Chupka in PA). They were only $7 a piece back then. I have two that don't match anyhting in my files.
1. For a Mary Raptos, name at birth was Mary Birka, father's name Michele Raptos and mother's name Anna Kubek. Born 8/22/1896 in Czechoslovakia.
2. Mary Chupko born 1/12/1887 in Czechoslovakia. Father's name Andrew Saksa, mother Anna Lazar.
If any of this matches anything in your file I'd be happy to send them along.
