Thomas Mills Hudson
Joined the Church in England. Traveled to Utah by 1851. The first documentation to place them in Utah is Mary's patriarchal blessing which she received in Salt Lake City on 24 January 1852. Her name on that record is "Mary Gailey" indicating that she and John Gailey were married prior to 1854. As such, the marriage date listed on FamilySearch may be incorrect.
George's obituary states they came to Utah in 1849. His sister's mentions they came in 1854. More research is needed to determine when and with whom they came to Utah.
