According to my birthday book, my great grandmother's maiden name was Genevieve Zdanciewicy and she was born in 1901. She had two brothers, Stanley and Sylvester. It is assumed that she lived in, or came from Pennsylvania.
I have been unable to locate any other Zdanciewicys and the name "Daniszewski" is the closest I've found to it. Do any of you recognize the spelling at all?
