Agnes Davis
Agnes traveled overseas on the ship Charles Buck, with her sister Elizabeth Davis Campbell and her family. It is likely that Agnes continued on with them in the Milo Andrus company in 1855, but further documentation is needed to determine that for sure. So far, the first documentation we have that places her in Utah is her marriage to James Ure on 25 March 1856, which was prior to that year's emigration season.
Her death date is confirmed by her obituary.
