Hannah, Agnes, and Rosanna Smart sailed to America in 1860 on the ship Underwriter. The ship manifest shows her as a "spinster."
She married Benjamin Williams in August of 1860 in Ohio. We know that the family arrived in Utah in 1863 or 1864 because a child was born in Ohio in September 1862, and their son Edwin, was born in Utah 1 January 1865. Further research is needed to determine the year of the family's travel and the name of the company they traveled to Utah with.
