His parents were working-class Lemko emigrants from Mikó, Austria-Hungary (now called Miková, located in today's northeastern Slovakia). Warhol's father emigrated to the United States in 1914, and his mother joined him in 1921, after the death of Warhol's grandparents. Warhol's father worked in a coal mine. The family lived at 55 Beelen Street and later at 3252 Dawson Street in the Oakland neighborhood of Pittsburgh. The family was Ruthenian Catholic and attended St. John Chrysostom Byzantine Catholic Church. Andy Warhol had two elder brothers—Pavol (Paul), the eldest, was born before the family emigrated; Ján was born in Pittsburgh. Pavol's son, James Warhola, became a successful children's book illustrator.
