While trying to find my ancestors I acquired copies of the Church records of births, deaths and marriages for Szczurowa Poland which contain records of many Kijaks from 1780s through 1872. Unfortunately, I later discovered that my ancestor Jozef was actually from a different town, Borzecin, which is nearby (so probably still related to the Szczurowa families). Now I have to order those records.
I also have some information on other Kijaks in Chicago, IL
