Quentin,

I have indexed most of the church and civil record books for gmina Bukowsko including the villages of Pobiedno and Dudyńce:

You might also find some information on my own web site: www.polishfamily.com under RECORDS ...

Łukasz, I have indexed most of the records from the Bukowsko gmina: https://www.semanchuk.com/gen/ church records only go back to Marriages 1787. Przemyśl Archdiocesan Archive has a few records circa 1890. And now that there is a new Archivist, we have access to those records.
