My G Grand Father Emil Gross was born in April 7, 1871 to Adolf Gross & Cacilia Konig, a Jewish Couple in Czech (formerly Bohemia).
Sadly, in Feb 16, 1875 his mother died of Typhus.
Emil was than raised as a Catholic in an Orphanage.
He never even knew he was a Jew until a Nazi SS officer found his documents and told him before WW2.
No one in my family ever knew which Orphanage it was.
But a Residence Permit by Prague Police Headquarter attached locate this family in Josefov Area.
So i believe the orphanage couldn't be too far from there.
As i'm currently working on my Mom's Paternal side family genealogy, any help would be highly appreciated.
