Interesting...
The information I have on Jozef Iskrzycki, b. 11-1899 d.1965
married Aniela Zybura and had 7 children, Piotr, Antoni, Weislawa, Grzogorz, Malgorzata, Zigmunt, and Adam.
He also was married to Franciszka Bury, children:Stanislaw & Wladyslaw.
Does any of the other information match yours??
I do not have a Helen Sawicki at all.
I received my information from Jozef Iskrzycki, b 7/1960 who currently lives in Rzeszow, Poland.
Jozef is my father-in-laws first cousin.
Let me know if you see any links!
