Anna Wampfler

British Mission Record, as seen in Mormon Migration, indicates that Anna and her three adult children (Susanna, Magdalena, and Jacob) were planning on sailing to the United States in 1866 via the ship Caroline. On the overland company records, the roster simply says "S. Klosner & Daughter." 

We know that both Magdalena and Jacob died en route. Their deaths likely occurred before the company roster was written up, which would likely explain why their names were not included, and Susannah's name (or the "S.") was likely mistakenly used instead of her mother Anna's first initial.
