Editing Tualatin, Oregon (section)

==History==
The name of the city is taken from the [[Tualatin River]], which flows along most of the city's northern boundary. It is probably a Native American word meaning "lazy" or "sluggish" but possibly meaning "treeless plain" for the plain near the river or "forked" for its many tributaries.<ref name="McArthur">{{cite book|last=McArthur |first=Lewis A. |author2=McArthur, Lewis L. |year=2003 |title=Oregon Geographic Names |edition=Seventh |publisher=Oregon Historical Society Press |location=Portland, Oregon |page=971 |isbn=0-87595-277-1}}</ref> According to ''[[Oregon Geographic Names]]'', a post office with the spelling "Tualitin" was established November 5, 1869, and the spelling changed to "Tualatin" in 1915.

In the 1850s, the settlement was first called ''Galbreath'' after its founder Samuel Galbreath. In 1853, Galbreath built the first bridge over the Tualatin river, and the town became known as ''Bridgeport''. In the 1880s, John Sweek platted a town around the new railroad depot, and named the town ''Tualatin''. It was incorporated as the City of Tualatin in 1913.<ref>{{Cite web|url=https://www.tualatinoregon.gov/community/tualatin-history|title=Tualatin History &#124; The City of Tualatin Oregon Official Website|website=www.tualatinoregon.gov}}</ref>
