The name of the area predates the revolutionary war. The location "Ong's" appears on a 1778 map of Hessian encampments in New Jersey. According to
Forgotten Towns of Southern New Jersey by
Henry Charlton Beck, Ong's Hat was a real village. According to Beck, around the 1860s, Ong's Hat was a lively town and served as a social center for the surrounding area. It was known for the availability of
alcohol and one of the first arrests of a
bootlegger occurred at Ong's Hat.
Prizefighting was also popular. Beck says that a
Polish couple, the Chininiskis, moved to Ong's Hat in the early 20th century. By that time only seven residents remained. The Chininiskis disappeared soon after. Years later, hunters found a female skeleton at Ong's Hat, which police speculated was that of Mrs. Chininiski. Tracking Mr. Chininiski to New York but unable to prove anything, Burlington County Sheriff
Ellis H. Parker kept the skull in his office for many years as a reminder of the unsolved case. In his 1944 book
Jersey Genesis, Beck himself says in reporting on Ong's Hat he fell for "elaborate traps" and that the story he had earlier repeated was a "fairy tale". He then subscribes to the explanation that the name is a corruption of Ong's Hut, a stopover point for a farmer from Little Egg Harbor. ==Urban legend==
