A great aunt of mine seems to recall that her mother, Stanislawa Olszewska, was born in or near a town named Lubowicz near Bialystok, Poland to a Michalina Tyminski Olszewski. Stanislawa's father was Josef Olszewski.
This is all I have to go on right now but I'm going to post it anyway.
Do any of these names or places make sense to anyone?
Thanks for reading my query.
