Hi Krista,
see Census 1930 with wrong spelling for Niemczyk;
https://familysearch.org/pal:/MM9.1.1/X78J-469
Jozef immigration year was 1913.
From marriage you have Jozef birth year, father name Michal Niemczyk, mather name Katarzyna Niemczyk.
Surname Niemczyk is popular in Giedlarowa - I probably found the tomb for Katarzyna Niemczyk;
http://www.giedlarowacmentarz.pl/?s=niemczyk
[in 4 row] Katarzyna Niemczyk d. 08.09.1931 [Sep. 8,1931].
Fresch flowers means, that somebody from Katarzyna and Jozef family is still living in Giedlarowa.
I am not related to Niemczyk and I am not from Giedlarowa.
I will look, how I can help you in search.
Cordially.
