Unlike his brothers, Brigham Young Jr. would later become part of the Quorum of the Twelve Apostles four years later in 1868, after the death of Heber C. Kimball and George A. Smith joining the First Presidency. In 1868, he was also a Representative to the Territory of Utah Legislative Assembly. Young Jr. also served as a counselor to his father in the First Presidency of the church from April 8, 1873, until his father's death on August 29, 1877.
