The park is named after John Kentwell, the fourth son of William Kentwell who migrated to Australia from England on the 3rd Fleet. Granted 60 acres of land in 1823 at the young age of 16, John was the original owner of the heritage cottage still standing at 244 Old Northern Road, Castle Hill. John Kentwell died at the age of 93, a well respected and model citizen of Castle Hill.
