Hélène Iswolsky

Hélène Iswolsky (, born in 1896, Tegernsee, Germany; died in 1975, Cold Spring, New York, United States) was a Russian noblewoman, anti-communist political refugee, writer, translator and journalist. Raised Russian Orthodox, she was received into the Catholic Church in France and later became an oblate, taking the name Sister Olga.

The American novelist Flannery O'Connor, who "used to go with her nephew", later described Iswolsky as "a Catholic of the Eastern Rite persuasion and sort of one-man Catholic ecumenical movement". Provided by Wikipedia
