John (Ivan) Potiahaylo
From rukapedia
My great-grandfather (my father's mother's father).
We're currently unsure of the spelling of the last name Potiahaylo. It was changed arbitrarily to Pothalo by the immigration authorities and that family name was used on the children's birth certificates.
Birthplace
Born in the village of Sarafinchi (alternate spellings: Serafince, Serafin'tse, Serafińce, Serafintsy, Serafin), birth date unknown.
