My grandma (who died before I was born) was Olga Rauch(ova)who's mom was Anna Rauch(ova).Olga was born in Vienna VIII., Austria on 2/28/1894. Anna was probably Czech (Tachau, Czech Republic)and Olga was raised by a foster family in Czech Republic. I would love to know more about Olga's father or Anna's life story. Please, can you guide me where I can find info that would help me with my search? I hope there is a way to access archives in Austria but I also wonder if Olga was born out of wedlock the church maybe didn't register her birth.
Thank you very much for your help!
