The Johnson family came to Utah sometime between 1863 and 1865. They sailed to America in 1863, but the first documentation to place them in Utah is a child born in March 1866, prior to the arrival of that season's emigration. Further research is needed to narrow the year of their travel; some sources list their surname as "Johansen" or "Johansson" and her middle name as "Sophie."  

Her name is listed as "Anna Sophia Peterson" on her death certificate.
