In her old age Emma continued to grow weaker. By April all of Emma's children found their way to the Mansion House in Nauvoo. Joseph III kept a "day-by-day account" of Emma's declining health. During the night of April 29 Joseph III saw "his mother rise herself up and extend her left arm. 'Joseph!' [he] heard her say. 'Yes, yes, I'm coming.'" Emma died at 4:20 a.m. on April 30, 1879. 
Her memorial service was held on Friday 2 May 1879 in Nauvoo, Illinois. Asleep in Jesus! Blessed Sleep! was amoung the hymns sung by the choir that day. Today Emma lies in Nauvoo, next to Joseph and Hyrum.
