Helmuth was related to Henry Robert Percival (1854-1903), a Episcopalian clergyman and theologian. In 1880, Percival briefly served as rector's assistant at Christ Chapel and then was rector of the Church of the Evangelist. In 1890, he founded the Anglo-Catholic St. Elizabeth's Church in Philadelphia.
