Cumorah's Southern Messenger reports David O. McKay lifting the genealogy requirement for ordination in South Africa.
"Leroy H. Duncan," Cumorah's Southern Messenger 45 no. 12 (December 1970), 323
President McKay provided a great blessing to the South African Mission Membership, when he granted the Mission President [Leroy Duncan] the right to bestow the Priesthood on male members, without the necessity of tracing their genealogy. Previously men were required to trace their genealogy from the Continent of Africa before they could receive Priesthood. This blessing resulted in more Priesthood bearers being ordained so that they could assist in local leadership and leave the missionaries free for proselyting.
