*** jv chap. 7 p. 89 Advertise the King and the Kingdom! (1919-1941) ***
Brother Rutherford was survived by his wife, Mary, and their son, Malcolm. Because Sister Rutherford had poor health and found the winters in New York (where the Watch Tower Society’s headquarters were located) difficult to endure, she and Malcolm had been residing in southern California, where the climate was better for her health. Sister Rutherford died December 17, 1962, at the age of 93. Notice of her death, appearing in the Monrovia, California, Daily News-Post, stated: "Until poor health confined her to her home, she took an active part in the ministerial work of Jehovah’s Witnesses."
Rutherford did not live with his wife for years even when they were both in California (Beth Sarim was in California). Malcolm has since died and I don't think he had children.
No children for the other two.
Most Bethelites that are old-timers, while married, have not had children since that would mean leaving Bethel and whatever "privileges" they might have.
