History

Allentown was incorporated as a borough by an act of the New Jersey Legislature on January 29, 1889, from portions of Upper Freehold Township, based on the results of a referendum held that day. The borough was named for settler Robert Burnet's son-in-law, Nathan Allen or for William Allen, who served as Chief Justice of the Province of Pennsylvania.
