Two of my grandparents are buried in the Mount Sinai Plot of the Mount Judah Cemetery - Louis and Mamie (Stein) Reische. I've hit a stone wall in determining where Louis came from originally, although evidence points to the vicinity of Rzeszow Galicia (now Southeastern Poland). I've checked both with the Cemetery itself and with the current adminstrator of the temple to see if the Plot was allocated to a specific lamdsmannschaft but they have only information linking the Plot to Mount Sinai Synagogue, none of it furthering the inquiry.
Is there anything in this limited information that would hint at the country or region of origin? Am I missing some obvious source of information?
