| Jackson | town and county seat, central Northampton County. Alt. 131. Inc. 1873. Settled prior to 1741 and known as Potecase Bridge. Made county seat in 1741 and known as Northampton Court House until renamed Jackson in 1826, presumably for Andrew Jackson (1767-1845), recent unsuccessful Democratic candidate for president. In 1808 the General Assembly had authorized the county seat to be named Atherton, but apparently the name was never adopted. It probably was intended to honor Maj. Jeptha Atherton, member of the Provincial Congress and the General Assembly. Produces lumber. |
