Hi Listers, My Nicholls family lived/worked farms at Freemans Reach on the Hawkesbury from the 1840's to 1952. The family also owned some land along the "Highlands" which were/are located between Wilberforce and Freemans Reach and between the old Common and Bushells lagoon. The Highlands were thought to be safe from flooding, but in 1867 my g-grandfather, Frederick Nicholls and his wife Jane[nee Martin], were rescued by boat from the attic of their Highland house, which was located on the first ridge above the lagoon. When I was living on the farm which went down to the Hawkesbury, older members of my family always said the land along the river was the true Freemans Reach [similar to all the other Reaches on the Hawkesbury] and the hills towards the north, which is called Freemans Reach today, was called Blacktown because of an earlier Aboriginal settlement along the Blacktown road which runs from near the top of Gorricks lane towards the Highlands. Best regards.........Ian Nicholls.
