Just learned recently from my mother, Antoinette (Toni) Yerskey Yonchak of family name "Yavorsky". Her Dad,
John S. Yerskey, was a boilermaker and lived/died in Farrell PA. He had brothers Albert, Andy, Steve ("Pip"), Louis, Frank, George ("Pure"), and several sisters. His wife was Anna Medvec Yerskey. For some reason, my grandfather spelled his last name YERSKY, but rest of family spelled it YERSKEY. Albert's family still lives in Farrell PA; George's family has some folks living in TX, others in Sharon/Hermitage PA area. Pips' daughter still lives in same home in Farrell. Family (Yavorsky's and Yerskey's and Yersky's) attended St Ann's Church, Farrell PA, and are buried in church cemetery, in Hermitage PA. I have more data, willing to share all. I can be reached via email at email@example.com
or via firstname.lastname@example.org
Hope to hear from you.
