I know of two sisters Eva Krupiak (1886 - 1940) and Xenia Krupiak (1883 - 1963). Their mother was Anna Natkowich (born about 1860). Both sisters named their first born son Andrew, so I would speculate that their father was named Andrew, but I have found no proof of this.
In the 1910 census, Xenia (Sadie) stated that she had come into the US 8 years ago (so 1902). Family lore states that her and her sister came over together and were first living in New Jersey (I don't know where.) I have found no immigration records.
Records state that she was from Jaworki, Novi Tohr, Austria (which would be in the Carpathian mountains, now in Poland.)
The cyrillic letters have been recorded in America as Xenia, Ksenia or Kzenia, it has also been listed as Kzenja.
The westernmost part of the Lemko Region extends into Nowy Targ county, where there is an island of four Lemko villages: Czarna Woda/Chorna Voda, Biala Woda/Bila Voda, Szlachtowa/Shljachtova and Jaworki/Javirky. Xenia called herself Ukrainian but they would be an ethnic minority of Rusyn or Lemko. (Kind of like the Basque people are neither French nor German.)
I can find Xenia and her husband Damian Pronchick in an error laden 1910 cenus.

It would seem that our families probably knew each other, certainly came from the same general area, but I don't see any connection at this firstname.lastname@example.org
