Genealogy / Searching for information on where to find 1880's birth records for Lachawa, Poland [14]

I am looking to find birth records dating to the late 1880s for Lachawa, Poland. My grandparents were born there. I had visited the area where the village once stood. Does anyone know how to get birth records from this area? I have been told records may have been at one time in Sanok, but were possibly destroyed during WWII.
