European and English settlers arrived here in 1713 in what was originally part of the colonial precincts of Carteret and New Hanover. Onslow County was formed in 1734 and was named for the Honorable Arthur Onslow, Speaker of the British House of Commons. After a lethal 1752 hurricane, the county courthouse was relocated from Town Point to Wantland’s Ferry; this settlement was eventually incorporated in 1842 and named Jacksonville after President Andrew Jackson. Largely a collection of sparsely populated agrarian and maritime communities, Onslow County dramatically changed in the early 1940s with the establishment of the United States Army Camp Davis near Holly Ridge (now defunct), and the creation of Camp Lejeune in 1941.
