I turn to researchers who have some ancestors in the German city of Oberhausen, Rheinland, Prussen.
I wonder if it's not in your family history that any of your ancestors (or his relatives) have an illegitimate child with their maid.
The point is that my great-grandfather's mother (Jewish from Poland, Cielcza - Jarocin) worked as a maid and became pregnant. She said, that she must not and will never say, who the father of the child is.
When she gave the child up for adoption, she told the adoptive parents, never to forget that the boy is Jewish. I believe that his father was also a Jew, because my mother, whose boy was a grandfather, is also according to DNA 1/4 Ashkenazi jewish.
So I try to find my family (just for know where I come from, nothing more, nothing less)
the maid's name was Agata Podsadna, born 8.2.1878
the boy was named Kasimir.
Thank you for any help.
