Heber C. Kimball was a central figure in early Latter-day Saint history, serving as Brigham Young’s first counselor and helping shape the church’s westward migration. He led a complex family life with 43 wives and 64 children, balancing loyalty, faith, and leadership amid the challenges of polygamy and frontier life. His daughter, Helen Mar Kimball, navigated personal tragedy while leaving a rich record of her experiences, and her son, Orson F. Whitney, carried forward the Kimball legacy through poetry, preaching, and church leadership. In this interview, biographer Andrew Kimball explores the lives, struggles, and enduring influence of the multi-generational Heber C. Kimball family.
