History
An 1834 description read, "Jenny Jump, a noted eminence in the northern part of Oxford t-ship, Warren co., extending N. E. and S. W. for about 10 miles, and into Independence t-ship."

In popular culture
Children's author John R. Neill, who regularly illustrated the sequels to L. Frank Baum and Ruth Plumly Thompson's Wizard of Oz series, before taking over the writing himself, lived in New Jersey during his last years. He gave the name Jenny Jump to his signature character, an adventurous New Jersey girl who first appeared in The Wonder City of Oz (1940).
