King County kept its name but changed its namesake: a 2005 law (Senate Bill 5332) made the Rev. Dr. Martin Luther King Jr. its honoree in place of William Rufus De Vane King.
Grays Harbor County was called Chehalis County until it was renamed in 1915.
Clark County was spelled "Clarke" in territorial and state laws from 1854 until the Legislature corrected the spelling in 1925.

Where Washington's 39 counties came from
Oregon's governments created Washington's first counties. In August 1845 Oregon's Provisional Government made all land north of the Columbia River into Vancouver District, and in December it split off Lewis County. When Congress created Washington Territory in 1853, eight counties lay north of the river. The new territorial legislature created many more in its first session in 1854, which ended with 16 counties. Seven more date from 1883 alone, among them Adams, Douglas and Franklin. Pend Oreille, the last, was cut from Stevens County in 1911 after residents complained that a round trip to the county seat at Colville took three to four days. Later breakaway efforts failed. In 1998 the state Supreme Court ruled that creating a county is up to the Legislature, and only after a petition signed by a majority of the area's registered voters.
