of holidaying in this rather isolated mountain retreat. They functioned on a modest scale bringing a rather select group of visitors. Meanwhile, a small number of property owners turned to orcharding to derive an income from this same mountain. Others, like the Whites of Withycombe, continued to use it as a summer retreat (Reynolds, 2009, 1,4-8, abridged) Following the death of Colonel R.O. Wynne on 24 September 1968, his widow, Florence Mariamne Wynne, Sons Mervyn Owen and Ronald Michael Wynne and daughter Jane Mariamne Smart became the new owners of the estate. On 3 May 1972 following the death of Colonel Wynne's widow, the three children inherited the estate. Gowan Ross Pty Ltd., established by the Smart family, purchased the estate. s polythene-clad tunnel houses in a nursery area east of the house were built by Bill Smart for use by the family nurseries. These were built on the site of the old tennis court. Bill Smart was interested in contemporary horticulture. Historic notes: The property of Wynstay somprses the largest land holding in the town Mount Wilson. Richard Wynne, a successful Sydney businessman, built MOunt Wilson's first cottage, which he named Wynstay, in 1875. Wynne set out to establish a park-like estate on the property in the English pictureesue tradition. To this end he acquired the largest land holding in Mount Wilson, on top of a hill that is now a dominant position in the settlement. Wynne built a second and larger cottage. Yarawwa, and later a larger U-shaped timber residence with a verandah on the three sides. This structure seerved the needs of the Wynne family until 1923 when Richard Wynne's grandson built the present Wynstay, a large sandstone house in the Georgian Revival style. The property is today owned by Mr & Mrs Smart; Mrs Smart is a direct descendant of Richard Wynne.
