Dobrij den Olyu,
Your father's selo/village Tysovytsia/ Тисовиця was/is a BOYKO village.
The Boyko/Bojko are a distinctive micro-ethnic group of Ukrainian Carpathian Montagnards of the Carpathian highlands. The Boykos inhabited the central and the western half of the Carpathians in Ukraine, including the Dolynskij and a part of the Rozhniativakisj raions/district > Ivano-Frankivska oblast/region, theSkolivskij , Turkivskij, and parts of theDrohobytskij, Sambirskij and Starosambirskij raions > Lvivska oblast, and parts of the Mizhirskij raion >Zakarpatska oblast as well as the adjacent areas of and .NE SlovakiaSE Poland
In recent times some scholars have claimed that this group is a part of Rusyn ethnos. However, the Boykos call themselves Ukrainians. Indeed, in the 19th century and in the first part of the 20th century Boykos, as well as most of the population of the present day's called themselves Ruthenians/Rusyny (pronounced RU-TEENY, not Russiany). Then the term UKRAINIAN, that replaced the term RUTHENIAN in a century earlier, became more common among /Ukrainians, including Boykos, as well. According to the recent census practically all Boykos in declared their ethnicity as Ukrainian.UkraineWestern RutheniansEastern UkraineWestern Ukraine
The name, BOYKO is thought by some to originate in their patterns of speech, specifically the use of the expression, "bah!".
Most Boykos belong to the Ukrainian Greek Catholic Church, with a minority belonging to the Ukrainian Orthodox Church. The distinctive wooden church architecture of the Boyko region is a three-domed church, with the domes arranged in one line, and the middle dome slightly larger than the others.
