The first documentation to place Edwin in Utah is his marriage to Elizabeth Allen in Salt Lake City on 1 October 1864. His name does not appear on the 1860 Utah census, so it is likely that he arrived between 1861 and 1864. Further research is needed to determine year of his arrival in Utah and the name of the pioneer company with which he traveled.
FamilySearch shows his birth date as 30 November 1838. The inscription on his gravestone shows his birth date as 30 November 1837.
