Looking for information on the Grossman family in Castrop Rauxel before World War II. Sigmund (Somer), Dora (née Kessler) and Edmond Grossman. Mainly I miss the name of Sigmund's father. And any additional information about them will help me a lot. Can someone help me find information about them ] and other family members on the Grossman side. They immigrated to Germany from Poland. Great appreciation!
