1952 The arrival of Al-Anon

"In loosely organized Family Groups, loved ones of A.A. members had gathered together and shared their experiences since the Fellowship's earliest days. At Bill W.'s urging, his wife Lois moves to create a separate fellowship that will formalize these meetings. With Anne B., who had initiated a Family Group in Westchester County, New York, Lois sends a letter to 87 such groups suggesting that they unite under the name of Al-Anon. The response is positive, and Al-Anon Family Groups is born. In January 1952 Lois and Anne shift the growing organization's office from Stepping Stones to the 24th Street Clubhouse in Manhattan."
