The area of Washington Township was purchased from the Sac and Fox Tribes
in 1842. The current township was formed in April 1852, but originally it
incorporated Grant, Chester and part of Sheridan, Malcom and Pleasant
Townships.
The first settler is thought to be William McNabb who entered land in
October 1848. He settled in a location that became known as Blue Point. The
George Beeler and Robert Carpenter families soon followed. The first church
was built at Blue Point.
A second community called Westfield was formed near Lattimer’s Tavern,
and now is part of Grant (formerly Grinnell) Township.
One of the oldest churches is the Friends Church on Sugar Creek at the
western border of the township. A cemetery was built there, then moved a way
up the hill, but some burials remain at the old location. The Blue Point Union
Christian Church was built in 1869. Another church was built at Oak Grove.
Jacob Switch was another settlement, settled by people from Illinois, in
the northeastern part of the township. Two railroads were built in the
township: The Iowa Central in 1870 from north to south, and the
Grinnell-Montezuma Railroad in 1875. Oak Grove was on the Iowa Central line
and Jacobs Switch on the Grinnell-Montezuma line.
