In Nauvoo, Snow again made her living as a school teacher. After Smith's death, Snow claimed to have secretly wed him on June 29, 1842, as a plural wife. Snow wrote fondly of Smith, "my beloved husband, the choice of my heart and the crown of my life". However, Snow had organized a petition in that same summer of 1842, with a thousand female signatures, denying that Smith was connected with polygamy and extolling his virtue. As Secretary of the Ladies' Relief Society, she organized the publishing of a certificate in October 1842 denouncing polygamy and denying Smith as its creator or participant. Years later, when Snow was informed that Smith's first wife, Emma, had stated on her deathbed that her husband had never been a polygamist, Snow was reported to have stated she doubted the story but "If ... was really [Sister Emma's testimony she died with a libel on her lips".
