John Wilson and his wife, Margaret, emigrated to the United States some time between 1841-1845. They have yet to be identified on any ship manifests. Some of their adult children also emigrated, but it appears that they each traveled independently of John and Margaret.
They reached Salt Lake some time during or before December 1854. John and Margaret were rebaptized in the West Jordan Ward on 20 December 1854. In Salt Lake on March 26, 1856, John was ordained a high priest. (See M251.33 H6382 for more information.)
More research is required to determine when they arrived in Utah and with which company they traveled.
