his second son Samuel Otoo who himself became a pastoralist. After receiving the land grant from Governor Macquarie in 1812, Hassall named the property Macquarie Grove and built the original farmhouse (now Hassall Cottage) in an elevated position beside the Nepean River in . Governor Macquarie was to visit the farm in 1815 during a tour of the Cowpastures region and, after camping overnight, referred to the property as "Mr Hassall's finely appointed and beautiful farm". With the development of the farm and the formal establishment of the Camden township in 1840, Hassall went on to construct a larger homestead to the south-west of the original farmhouse'. Following Rowland Hassall's death at Parramatta in 1820, his son, Samuel Otoo, inherited the Macquarie Grove property and occupied the farmhouse (now Hassall Cottage) with his wife Lucy Mileham and family. At this time, Macquarie Grove was the most established and valuable property owned by Rowland Hassall and Samuel continued to run the property as his father had done. With the development of the farm and the formal establishment of the Camden township in 1840, Otoo's son James Mileham Hassall constructed a larger homestead on the property to the south-west of the original farmhouse. The new homestead was called "Macquarie Grove" and the farmhouse renamed "Lucyville". Following Samuel's early passing at aged 33, Lucy remarried and moved away from the property, only returning in the late 1840s to occupy Lucyville following the death of her second husband. Also at this time, Mileham Hassall, was occupying the Macquarie Grove homestead with his family but, following the damaging floods of the 1860s, James moved his family and leased the property to the schoolmaster William Gordon for its use as a boys' school. As the Hassall family fortune dwindled, James sold the Macquarie Grove property (and both cottages) to Henry Carey Dangar MLC, the prominent pastoralist, property owner and racing enthusiast in 1877. Macquarie Grove was not intended to be a commercial venture for Dangar but rather to become the family's summer retreat for three months each year and also the produce provider for their Sydney home. As well as producing butter, eggs and poultry, the farm also provided for the farm stock and the retired race and carriage horses that grazed the property. At this time, a portion of the Macquarie Grove property was used as a rifle range by the Rifle Club of Camden.
