The Andersen family came to Utah between 1863 and 1864. They likely came in 1863, the year Peter took out a PEF loan and they sailed to America. The family sailed to America in 1863 on the ship John J. Boyd. The ship manifest shows their surname as "Andersen."
The first documentation to place them in Utah is a church ordinance for Peter and Hanne in July 1865, which was prior to the arrival of that season's emigration. Further research is needed to narrow the year of their travel.
Her death dertificate shows her name as "Hanna J. Anderson."
