A week prior to each General Conference the Relief Society meet for an evening. When was the first time this happened in the Church?
George Washington Hill baptizes Sagwitch (May 5, 1873), the leader of a group of Shoshone Indians, and 101 of his tribe in the Bear River in Box Elder County, Utah. This is the beginning of an important relationship between the Church and the Shoshone. From this group came one of the first Native Americans to be called as a full-time missionary (Sagwitch’s son) and the first Native American called as a bishop (Sagwitch’s grandson).
