It seems we are both searching the same surname of KANIA.
Since you mentioned Rzeszow, I thought I'd contact you . I plan on spending a week or so in that area next year trying to research both sides of my family. My main interest will be around Jarsloslaw and Lviv Ukraine, since this was the Galicia area in those days and it ran from Poznan to east of Lviv ,Ukraine. My Dad was born in 1892 and I know he hada brother and some sisters . If I find out anything more on the Kania Name I'll let you know. Ray
