The area was first settled for farming purposes to supply produce to the early Sydney settlement. Supplies came in and produce went out by boat exiting Mangrove Creek into the Hawkesbury River at Spencer. Given the pristine location, fertile soil and the ready supply of fresh water from the creek, this area would have been invaluable to the settlement.
Many of the families who settled Mangrove Creek have direct bloodlines to those who arrived on the First Fleet and particularly to Matthew Everingham whose life has been detailed in three publications of author Valerie Ross (The Matthew Everingham Story, the Hawkesbury Story and Cornstalks). Alfred Andrews married Amanda Green who brought those bloodlines to the Andrews family. Other notable names in the Valley include Woodbury, Douglas, Pemberton, Ferguson, Starkey, Everingham, Mooney, Chaseling and Watkins et al.
There is evidence of road and bridgeworks of the early 1800s in the valley, much of it of convict origin. The area is also the former home of the Darkinjung people, direct descendants of whom still live in the vicinity.
Picnic races, dances, tennis and cricket were the main social activities in the area.
Following the resumption of all but one property by Council, buildings have gradually disappeared either by demolition, removal or by bushfire. Fairview remains the only relic of our history in this area and it has withstood the elements, including bushfires, for the last 90 years. Fairview and this beautiful valley must be saved for future generations.
