L. Hancock recalls that Joseph told him to take Alger to Missouri.
Levi Hancock, Autobiography (Part 3) [ca. 1896], 57, CHL, MS 570
I worked at my trade through the summer, nearly when I heard that the people of Clay County were about to drive our brethren from that county. It was about this time I received a letter from Solomon saying he had married another wife and was going to Missouri.
I saw the Prophet Joseph Smith and he told me to take Fanny Alger and go. I offered my place for sale and sold it before night. I made me a wagon of wood and got it iron rimmed on the wheels for Solomon and we started the latter part of August for his father-in-law's and got there about the first of September 1836.
