History
Formed in 1771 from Orange County
An old deed may name a county that no longer exists, or a boundary that has since moved.
Chatham County was created from Orange County in 1771 and named after William Pitt, 1st Earl of Chatham. In 1895, Chatham lost land to Alamance County when commissioners redrew the boundary south of the 1771 survey line, but the legislature repealed this change in 1897 after a local referendum. In 1907, Chatham lost additional territory to the creation of Lee County.
