Snohomish was founded in 1860 by E.C. Ferguson and E.F. Cady. The town quickly grew and prospored. Fine stores and homes were built as the town gained the County Seat (which later went to Everett). The town was originally known as Cadyville, and changed its name to Snohomish City in 1871. Snohomish was officially incorporated on November 24, 1883.
