My Buczko's came from Kurylowka also, at least according to the WW1 registration of one Michael Buczko. He was b. 8 Sep 1877 in Kurylowka, Galicia, Poland. He is actually one of three siblings, his sister Josephine being my main interest. She was b. 15 June 1893 in Galicia and I'm assuming Kurylowka. She m. Wojciech "George" Dec in 1911 in Hartford, Hartford Co., CT and d. there 27 Jan 1948. Her sister Christine (b. 1881) and brother Michael all came over and settled in Hartford. Their parents were Alexander Buczko and Kattryzyna Unknown and I have no vitals on either.
I see that there was another Alexander Buczko in Kurylowka but his kids don't match up with mine. If these names and dates ring any bells for anyone I'd love to hear from you.
