My grandmother (Anna Taras - daughter of Julia Wrona and Timothy Taras) came from Labowa. I know my mother has mentioned people with the surname of Pelak who came to Binghamton, NY. The Wrona family did come to America and settled in Shamokin.
I have been to Labowa twice and there is not much left of the town from when our ancestors lived there. The Ukrainian Army came through the town during WWII - burned the town and forced the residents out. I do have photos of the town as it is today. The Greek Catholic Church is still standing.
I am aware of the location of the Greek Catholic Church records from Labowa. I would be interested in talking to you about Labowa. You can contact me at firstname.lastname@example.org
