Polish names ending in "er"

I suppose these are somewhat rare names. Just how common are surnames ending in "er" these days in poland?

example: Treder , Szulfer

"er" endings is normally jewish f.ex. Skoller.Pincher,Gringer,Lesner and so on.

The above I posted are polish but i had no idea jews carried "er" as well.

szulfer seems to be a Jewish name as there were many Jews among the Kashubs in Poland.

Could be but certainly not the treders I know. Btw what do kaszebczi have to do with it

Yeah, I also think that these are surnames of Polish Jews.

Does anyone on this site have a Kashubian background?

Not only Jews! -er could also means German roots... My family name is Mitzner and it is'nt clear whether it's jewish origin or... else

Micek...........
Mitzner, Rivka a name from a israelian professor.
You also fouond Mitzner as a ewish surname in Galicija.........
Seems to be used by galician jews.

Maybe, but not only. My grand grand father was from Łódź and as you may know it was in Russian not Austrian part of Poland. Yes I know there are a lot of Mitzners all around the globe, but in Poland only my family (4 people).

Łódź was a city with plenty of jewish people .

German too

This year's awards went to Stefan Chwin for the novel Esther (see review below), Piotr Mitzner for poem collection Myszoser and Joanna Pollakowna for essay collection Glina i swatlo (Clay and Light).

Piotr Mitzner's poetry is characterized by numerous metaphors, unusual endings and lingusitc experiments, all of which helps him to write disturbing poems creating atmosphere of restlessness.
I can find many more Mitzner in Poland...........

German too.......
Yes - its naturally. A great part of the polish jews origin were from Germany.
There fore they had a special language;jiddish with lot of german inspired words...

Treder is a polish/ kaszub name not jewish. A short search show this. Franciszek Treder organized the Kaszub museum in Kartuzy. It's also a fairly common name in the kaszuby reigon of poland.
