Lucy Walker

“I am also able to testify that Emma Smith, the Prophet’s first wife, gave her consent to the marriage of at least four other girls [Emily and Eliza Partridge, Maria and Sarah Lawrence] to her husband, and that she was well aware that he associated with them as wives within the meaning of all the word implies.”

Andrew Jenson, Historical Record 6:230.

Benjamin F. Johnson

“I do know that at his [Joseph Smith’s] Mansion home was living Maria and Sarah Lawrence and one of Cornelius P. Lott’s daughters as his plural wives with the full knowledge of his wife, Emma, of their married relations to him.”

[1] William Law was positioned to know if conjugal relations had occurred between Joseph Smith and Maria Lawrence. Andrew Ehat reports that Law “found Joseph in a compromising situation with Maria on 12 October 1843” (Andrew F. Ehat, "Joseph Smith's Introduction of Temple Ordinances and the Mormon Succession Question." M.A. thesis, Brigham Young University, 1982, 132). Unfortunately the endnote (371 page 276) does not provide any additional evidence. I have been unable to ascertain whether Ehat was working from assumption of manuscript documentation.
