Standifird, John Henry, Diaries, 1862-1923, vol. 1, 2.
In March 1857 I started overland to Missouri. Fell in company with some Latter Day Saints who were emegrating to Utah. I investigated their Doctrines and was Baptised by William C[restfield]. Moody about 20 miles West or Southwest of Independence, confirmed by Homer Duncan.
The next day started with the Saints for Utah where I arrived 9, September 1857.
