I have been doing a long-term community study of the town of Labun (called Lubin in Yiddish and now known as Yurovshchina, Ukraine), which is 18 miles from Shepetivka. In 1921, a family of five children (Mania, Jankiel, Chaim, Mojze and Usla Fertel) arrived in the United States heading for their uncle Hyman Boris. They had all been born in Labun. Their parents were Abraham and Fannie (likely Feiga) Fertel. In the United States, the children took the surname Fetell. My research also indicates that they had an uncle in the United States named Ben Fetell.
My blog contains two posts regarding Fetell family members:

If you think this may be your family, please contact me privately and I will share more information and records.
