Records for Ostrytsya, Chernivitsi Oblast, Ukraine
My great-grandfather (John Warwaruk - John is his English name, we don't know his birth name) was born in the village Ostrytsya (outside of Chernivitsi) in modern-day Ukraine in 1886. When he emigrated, the village was part of the Austria Hungary Empire. His parents names were Maxim and Domnika Warwaruk.
My family is hoping to learn John's birth name, where his parents were from, if he had siblings, and what his grandparents names were. We've searched all available U.S. records about John, but it doesn't have any of that information. I believe we will need to get this information from the records of his village or Oblast. I have no experience researching records in that part of the world.
Does anybody have any suggestions of where I should look to find more about this Warwaruk family that lived in Ostrytsya in the 1800s? The family could also have roots in Bukovina. In John's U.S. naturalization papers it says he is from Ostrytsya, but in a 1910 census he says that he and his parents are from "Bukowina"; however, that could have just been the largest nearby city.
I greatly appreciate any help. Thanks!
