Dorchester, Iowa is located in Section 14 of Waterloo Township, the northwestern most township in Allamakee County. Waterloo Township contains an area smaller than any other Allamakee County township, except Fairfield on the Mississippi. Waterloo Township consists of30 full sections and a narrow strip to the north of only six sections south of the Minnesota state line. Waterloo Township was organized from Union City by an order of the Allamakee County Court, March 3, 1856.
Ellery M. Hancock in his history of Allamakee County notes that “The earliest settlement seems to have been made in the Northeast corner, in 1851, by Mrs. Jas. Robinson and her sons, on Portland Prairie.”(1)
