... President Grant was ordained a Apostle by Elder George Q. Cannon, who was ordained by President Brigham Young, and Brigham Young was ordained by one of the Three Witnesses to the Book of Mormon. We do not have any record as to which one of the Three Witnesses was voice in ordaining Brigham Young, but inasmuch as these three me were instructed by direct revelation from the Lord to choose the Twelve Apostles, and they assisted in their ordination, in connection with the First Presidency, the line of authority back to the Prophet Joseph Smith is complete.
