• Mary's obituary says she came to Utah in 1864 with her elder sister Ruth. They arrived in New York from Wales on 23 June 1864 via the ship The General McClellan. The British Mission Record (as documented in Mormon Migration) and the ship passenger list has them listed as Ruth P. Evans and Mary P. Evans. (Their father's name was John Evan Price.) However, the Warren Company roster lists them as Ruth and Mary Williams. This mistake in surname may have been made because they were traveling in the company of a the Williams family.

  Ruth and Mary also appear in Perpetual Emigrating Fund records under the surname Evans.
