The lands and Cowlitz River in and near present-day Toledo were once used by the Cowlitz people and other indigenous tribes as a means for sustenance, including fishing the waters, and as a transportation vector.
Simon Plomondon (or Plamondon), an employee of the Hudson Bay Company, settled in the area in 1820, taking up a donation land claim, marrying a Cowlitz Chief Schanewah's daughter, Thas-e-muth (Veronica). Plomondon became the first white man to settle in what would later be known as Southwest Washington. The couple's first child was born in what would become Toledo in 1821.
