Gracia Jones—a great-great-granddaughter of LDS church founder Joseph Smith—is among those trying to heal a long-standing rift between his descendants and those of Brigham Young. It all started with Smith's death in 1844.
While Young led the LDS migration to the Salt Lake Valley, Emma Smith remained behind and eventually re-married. One of her sons led a splinter group known as the Reorganized Church of Jesus Christ of Latter-day Saints. Consequently, none of Smith's descendants were affiliated with the original body of Latter-day Saints until Jones discovered her ancestry and joined 51 years ago.
Ill will has persisted among some descendants of the families for more than a century and a half, Jones said. When planning a reunion of their family members, Smith descendants "talked about the difficulty that children of the family had with Brigham Young and the harsh feelings that had filtered down and left a scar on the family because of the bitterness the children held against him," Jones said.
