 Mrs. Cornelius Vanderbilt Sr. ceased to worship at St. Bartholomew's following Parks's attacks on conservative elements within his own church.On the more-diplomatic side, in 1908, Parks convened a dinner meeting of New York church musicians, which continues to this day as St. Wilfrid Club, a longstanding organization of prominent organists.In 1878, Parks married Margaret Alden Haven, an expatriate then living in Geneva, Switzerland, and they became the parents of at least three daughters.
