Stefan Buczko married Marya Chuda c.1870 in Kuryl'o'wka or nearby. The village of Kurylowka is just North East of Lez'ajsk. I know of 2 of their children. Katarzyna and Michal.
I'm looking for other children they may have had and any information on the family. Is anyone else searching in Kuryl'o'wka or the Buczko or Chuda families?
