Colonel Isaac Neff Ebey (1818–1857) was the first permanent white resident of Whidbey Island, Washington.
Ebey was born in Columbus, Ohio in 1818. During his childhood Ebey's father, Jacob, moved the family to Adair County, Missouri where as a young man, the young Ebey was trained in the law. At age 25, Ebey married Rebecca Davis and they later had two sons, Eason (who became Phoebe Judson's son-in-law) and Ellison. Born with a naturally adventurous spirit, Isaac temporarily left his wife and young sons in Missouri to discover the American west - specifically the Pacific Coast.
During his journey west, Ebey briefly tried his hand at gold-mining during the California gold-rush and then headed north to Oregon Territory. After arriving in the Puget Sound region he went to work for the U.S. Customs service. While with the service, Ebey spent some time in Olympia, the city he is credited with naming in honor of the Olympic Peninsula mountains to the west of Puget Sound. Ebey also sponsored a statute to name King County, Washington.
