George and his mother, Abby, may have come to Utah with his sister Sarah Ann Scott in the 1851 Morris Phelps company, but further research is needed to confirm this. George sold property in Salt Lake City 13 March 1853. Further research is needed to determine the name of the company with which he traveled.
Census records show his surname as "Humphreys." In 1850 he was living in the household of John Huntington in Iowa.
His birth and death dates re confirmed by the inscription on his gravestone in Oregon, USA.
