Trabajo en un registro genealógico que abraca incluso la familia de mi abuela materna de apellido Kosteski. Me gustaría contactarme con personas de este apellido en Ucrania. La familia de Jacob Kosteski emigró de la aldea de TEREBOVLYA en el año 1900. Agradecería cualquier información

Thanks for ansewering my request. My grandfathers were members of the Greek  Catholic Church, and until now my family preserve ukrainian traditions. I have already asked in LDS Library:
weddings in Zascinosze. My great - grandfather was born there and moved to Humnyska. His parents lived in Zascinosze up to their deaths. Do you know how can I contact people living now in Ukraine?

It is my pleasure to meet people like you !_________________________________________

From late 18th century to 1919 your ancestral wies/village Zascinocze was hamlet size.  The village name is first mentioned in 1471 and means BEHIND THE WALLS.  It was settled on the banks of the Seret River. The filial Greek Catholic Church was in Ostrowczyk and the filial Roman Catholic Church was in Trembowlya.  Trembowlya was both the POWIAT/administrative district-county and GMINA/judicial-tax district.  Galicia/Halyczyna Province, administered by ethnic Poles for the Austro-Hungarian Empire. From 1919-1939 Tarnipolska  wojiwodstwo/region came under Reconstituted Poland's domain.  Technically for the previous 125 years, Poland had not existed as a geopolitical entity. Post WW2 this region became a part of SSR Ukraine, under Soviet domain, until 1991, when Ukraine became independent. (Trembowlya became Terebovlya in 1939.)
