While he was alive, Joseph Smith married the wife of Simeon Dagget Carter in Nauvoo. Lydia Kenyon Carter was listed as "Lydia Smith [--] wd of Joseph Smith (Prophet)," when she was sealed to James Goff on 8 June 1851. Born in 1799, she was 44-years-old (menopausal) when she became one of the Prophet's polygamous widows, after which Reynolds Cahoon sealed her as a polygamous wife to Heber C. Kimball on the same day the apostle sealed Cahoon to his first polygamous wife. The latter two had also married before the Prophet's death. Legally married to Simeon D. Carter since 1818, Lydia (mother of their three children) resided with him in Nauvoo and Utah --despite her marriages to Smith, Kimball, and Goff.
