History of Onslow County
European, mainly 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 Arthur Onslow, the longest serving speaker of the 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. Through much of the first half of the 20th century, the county was largely rural, with an economy based on agrarian and maritime communities. During World War II, Onslow County was 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. About 2,400 residents were displaced to allow for the acquisition.
