My grandmother had a stepbrother Henry ZITTLAU later changed to ZITTLAW. He was born in Poland, possibly Warsaw. The two shared the same father (Christian ZITTLAU), but I am trying to locate his mother who I believe is a SCHAFFRICK. I have sent for his death certificate. His son reported the information and listed the mother's and father's name as Unknown. Henry's son has since died so I cannot contact him. On the death certificate it says "no" for Social Security which I don't know if it means "not known" or "none". Does anyone have any ideas of how to locate his mother's name? I do have his correct birthdate but only a possible birthplace of Warsaw. It could only have been a location close to Warsaw, however, in 1876. He is not listed on the SS Death Index but does anyone know if you can request the SS for an application if you do not know a SS#? I would appreciate any direction.
