Question: What did the husband of Lucinda Pendleton Morgan Harris know about her sealing to Joseph Smith for eternity?
There are no records in existence that indicate that she was sealed to Joseph during his lifetime, only after his death
Lucinda Pendleton was married to Latter-day Saint George W. Harris. There are no records in existence that indicate that she was sealed to Joseph during his lifetime. It is known that Lucinda’s proxy sealing to Joseph Smith was performed in the Nauvoo Temple on January 22, 1846, after Joseph's death. In addition, she was re-sealed to Joseph in the Salt Lake Temple in 1899. Brian Hales notes that, "current evidence indicates that several of the women who participated in proxy sealing to the Prophet in the Nauvoo Temple were not married to him while he was living."
