Published version of William Walker's reminiscience and journal on his introduction to the practice of polygamy.
Elizabeth Jane Walker Piepgrass, ed., The Life Incidents and Travels of Elder William Holmes Walker and his association with Joseph Smith, the Prophet (n.p., 1943), 9–10
In the spring of 1843, my father, being away on a mission, the Prophet asked my consent, for my sister Lucy in Marriage. I replied that if it was her choice: that if she entered into the celestial order of marriage of her own free will and choice, I had no objection. This of course was in contrast with my former education and traditions. It also was altogether different from the course generally pursued by monogamists. Instead of taking a course to deceive and prostitute and bring about her ruin, he took a straight-forward, honorable, and upright course, in no way depriving her of her agency.
When father returned from his mission, the matter being fully explained in connection with the doctrine, received his endorsement and all parties concerned received his approbation.
