FYI most of Zaleschyky raion/district > Ternopilska oblast/region has not been filmed by LDS.You choices are limited to contacting archives yourself or hiring someone like Ihor Voronchak, native son, currently living in Lviv,who has done extensive research in Ternopil.He has also written a Book about surnames from this region. His prices are very fair, much better than directarchival inquiry. Additionally, the turnaround is much firstname.lastname@example.org. =============================== Dobrotvir is quite different than it was when your Immigrant Ancestors left.Today there is a large power plant there and that has attracted many new residents.
LDS has filmed both Greek Catholic (1835-1900) and Roman Catholic (1784-1900) Church Registers: https://familysearch.org/search/catalog/results#count=20&query=%2Bkeywords%3ADobrotwor
