Descendants Smith's descendants have played significant roles in the history of the Church of Jesus Christ of Latter-day Saints. Joseph F. Smith, his son by Mary Fielding Smith, served as president of the LDS Church from 1901 to 1918. His grandson, Joseph Fielding Smith also served as president of the church from 1970 to 1972. His eldest son, John Smith, served as the church's Presiding Patriarch from 1855 to 1911. John Smith's descendants held this post from 1912 to 1932 and from 1942 to 1979, when the office was effectively discontinued and the incumbent, Eldred G. Smith, was given the title patriarch emeritus. M. Russell Ballard, the current Acting President of the Quorum of the Twelve Apostles of the LDS Church, is also a direct descendant of Smith. In 1918, Smith's descendants erected a monument to him in the Salt Lake City Cemetery. In 2000, it was estimated that Smith had over 31,000 living descendants.
