It appears likely that this William Rodman, who was age 20 in the 1850
census is the same as Ted Hawken's ancestor William B. Rodman, who can
be found in the WorldConnect database (database name of thawken).
According to Ted Hawken's data, his William B. Rodman was born 7 Jul 1830
and his father's name was Hugh. The Hawken data states,
``William Rodman sold the Rodman farm and the family of 5 left
Sigourney, Iowa in 1864 and joined a wagon train leaving
Independence, Missouri.'' The wagon train was going to Oregon.
William died in Oregon on 25 Jan 1905 at age 74y, 6m, 18d,
and is buried at Wamic, Wasco Co., Oregon.
