Interesting piece of fiction. The LDS departure from Nauvoo was orderly and the only thing 'burned' was the temple by u/i arsonists. Emma and her family and the entire RLDS sect continued to live in Nauvoo in peace until they moved to Plano IL, in 1866.
Are you calling me a liar?
My family chose to leave Nauvoo after the riots brought about by the religious bigots.
My progenitor JL Heywood was one of the Mormons left behind to facilitate the sale of Mormon properties. He wasn't attacked or burnt out and he was able to conduct business with non-mormons.
When the Latter-day Saints commenced their exodus from Nauvoo in 1846, Heywood, along with Almon Babbitt and John S.Fullmer, was chosen as one of the trustees to supervise the disposal of Church property. After arriving in the Salt Lake Valley in 1848, he was named postmaster of Salt Lake City, Bishop of the Seventeenth Ward, and surveyor of highways in the provisional State of Deseret. He helped John M. Bernhisel at the nations capitol obtain a territorial government for Utah and was appointed U.S. Marshal for the newly created Utah Territory.
Panax...these family stories of heroism do NOT make Mormonism true or good. They are simply stories. Another of the progenitors is John D Lee. He was tried, convicted and executed for following his Mormon Militia orders an his part of the Mountain Meadows Massacre. He played the role of scape goat for a cult.
