Many years later in Utah she wrote a retrospective poem about this marriage from which we learn that it was "for eternity only," that is, unconsummated. Whatever such a marriage promised for the next world, it brought her no immediate earthly happiness. She saw herself as a "fetter'd bird" without youthful friends and a subject of slander. This poem also reveals that Joseph Smith's several pro forma marriages to the daughters of his friends were anything but sexual romps. Furthermore, the poem reinforces the idea that, despite the trials of plurality in mortality, a "glorious crown" awaited the faithful and obedient in heaven.
