Possibly traveled in the 1864 Warren S. Snow company per a few tertiary sources. More research is needed to find a primary source that confirms her participation in that company. Her parents emigrated to the U.S. the following year in 1865.
While it is possible that Jane traveled with the 1864 Warren company, it is just as possible that after reaching the U.S. that she spent a year in St. Louis (or another city) and worked and waited until her parents came to the U.S. in 1865, then traveled with them to Utah. Because she did not marry Robert Knight until 1868, it is more likely that she traveled to Utah in a later year than 1864.
