My great-grandmother came from this area of the Ukraine, I believe. Although I think it was either Russia or Poland at the time. The exact place my grandma told me her mother was from was this: Proskurow (Khmelnitski), Chsperchency, Russia.
Her maiden name was Letschuk. I can't find any record of that as a surname, so I think the spelling may be wrong. My great-grandmother, Paraska (Pearl) Letschuk, had three brothers: Andrew, Trofem, and Vladimar, and one sister, Christina. Their parents were Harry Letschuk, and Mary (maiden name unknown).
Paraska left Russia to come to Canada in 1909 with her first husband, Fred Mazur. Any information or help anyone can provide would be greatly appreciated!
PS--I'm told the spelling may have been closer to something like Lesczcuk.
