Hiram Page, one of the Eight Witnesses to the Book of Mormon, was married to Catherine Whitmer, daughter of Peter and Mary Mussleman Whitmer, making him a brother-in-law to both David Whitmer and Oliver Cowdery, two of the Three Witnesses.

Although Page and others in the Whitmer family eventually became disaffected from The Church of Jesus Christ of Latter-day Saints, neither he nor any of the other witnesses ever denied their testimony of the Book of Mormon.In 1847, Hiram wrote that his mind was not so "treacherous" as to have forgotten what he saw. Moreover, he noted that it would be "treating the God of heaven with contempt" to deny his testimony.

Hiram Page died in 1852 and was buried on the farm of his son, Philander Page, in Ray County, Mo.
