I am looking for a possible family connection between a Raich and a Luban (I am descended from a Solomon Luban). I have come across a Martin Raich who died in 1946 whose mother's maiden name was Luban. I am wondering if anyone knows about this Raich and who his mother might have been and where she came from. The Lubans I am related to are mainly from Milwaukee, WI and Los Angeles, CA.
