Your ancestors, judging on the basis of their names were most propably Greek-Catholics. There was a Greek-Catholic parish in Dabrowica but it was established in 1906. I am not sure where the parish was before that. Most propably in Ozanna (about 3 km from Dabrowica). Unfortunately I can not find any records for these parishes in state archives in Poland. It could also belong to Kuryłówka parish but it is a little further away (there are records for 1786-1866, 1869I in a state archives in Przemysl. You may try to contact local civil registry office (USC) in Kuryłowka, maybe they have some, at least most recent, records. Also, there is a church archives in Przemysl, they do not have too many metrical records but you may be lucky.
