Genealogy / Kwasny Joseph born 1891 Kalisz area [5]

I am helping a descendant of Joseph Kwasny who ended up in Illinois, USA.
He was born 9 march 1891 in ?? Osada, Londek, Kalisz, Russia Poland.

This information came from his draft card in 1917/1818. He was age 26 years.

He was a Tailor.

We are trying to trace his parents or any siblings as he did not leave that information in any documents that we have found so far.

I Understand that he would have come from the government area of Kalisz..but where or what would Osada Londek be?
Is the the correct forum for me to ask this question. It is my first posting. Is there other genealogy sites I should post this to.

I unfortunately only speak English.

Thank you
