I have a few on file now at the family reserach center. It's hard to read the language after 1910. It's in Ukrainian. Polish and Latin I can make out to a certain extent but not Russian or Ukrainian. There were a lot of famlies there pre 1900 and I don't know what happened to them all. Some came to the US but there were many Denega and Romanow famlies in that area and now I can't seem to find any connections. I've been away from my research for a few months. I have never tried writing to the district or region. I'm not sure they would have any info on a pre 1900 family.
