i am also trying to find information about my ancestry from Katowice. I actually visited once briefly in 1998. Let me know if you find an interesting source with information. Possible surnames were enoch or redner on my end i think. we're not quite sure, the names were altered when they arrived in the u.s. post wwii. i just rec'd some info on my polish side from a cousin who has amazing records. in my cousins chart, he has a johann but he was born in rawa ruska, poland. he was married in Chrzanow Poland (Krenau, Austria) but past away in 1942. doubt its the same one because kaleta and the other surnames you mentioned don't match any in my chart that i know of.
we have info about the following surnames from krakow, chrzanow, and katowice : marmor schneider mehler but not much about redner or enoch
if anyone out there reads this and a name rings a bell, please let me know...thanks in advance, Robyn
