Joseph Smith's father, Joseph Smith Sr., first occupied the hereditary office of Presiding Patriarch of the Church of Jesus Christ of Latter-day Saints. Thereafter, it became a focal point for struggle between those appointed and those born to leadership positions. This new edition of Lost Legacy updates the award-winning history of the office. Irene M. Bates and E. Gary Smith chronicle the ongoing tensions around the existence of a Presiding Patriarch as a source of conflict between the Smith family and the rest of the leadership. Their narrative continues through the dawning realization that familial authority was incompatible with the LDS's structured leadership and the decision to abolish the office of Patriarch in 1979. This second edition, revised and supplemented by author E. Gary Smith, includes a new chapter on Eldred G. Smith, the General Authority Emeritus who was the final Presiding Patriarch. It also corrects the text and provides a new preface by E. Gary Smith.

Irene M. Bates received a Ph.D. in history from UCLA. She died in 2015. E. Gary Smith is the son of the last Presiding Patriarch and is retired after being senior partner at Smith & Smith in Santa Ana, California.
