In the early 20th century many Rusyn immigrants from the Carpathian Mountains settled in Four Mile Run. Most came to work in Pittsburgh's steel industry, and the neighborhood was adjacent to a large steel mill of the Jones and Laughlin Steel Company. Thus they called their community Ruska Dolina, which translates as Rusyn Valley. In 1910 they established a church there, St. John Chrysostom Byzantine Catholic Church. The parish is famous today as the childhood place of worship for the artist Andy Warhol and his family, who lived in nearby Oakland.
