DEATH OF JOHN COBB
John Cobb died on 7th April 1840 aged 37 and Anambah was advertised for sale. The buildings mentioned in the advertisement were earlier constructions, not the one pictured below which was designed by architect J.W. Pender and completed in 1889.

Wentworth and surrounded by those of Messrs Hobler, Pringle, Mitchell, Marshall, Hudson and others, and containing in the whole two thousand acres. The improvements made by the late Mr. John Cobb, during his residence of twelve years on the property are both extensive and useful. The buildings consist of a comfortable and neat Verandah Cottage, containing eight rooms, with kitchen, laundry, nursery, dairy, barns, stable, coach house, blacksmiths and carpenters' shop, and other necessary buildings detached. Above one hundred acres of the ground is enclosed for tillage and forty acres now in wheat. The remainder is grazing land of the best description and well watered; there is also a garden in the front of the house, stocked with choice fruit trees. 
Maria Cobb remained at Anambah. In 1847 while walking alone in her garden one afternoon and although in perfect health, Maria was seen to fall down. Her daughter ran to see what had happened and was shocked to find her mother unconscious. An express was instantly sent into Maitland for Dr. Sloan who galloped out to the property, however she was found to have already died. The cause of death given as apoplexy. She was 41 years old.
Anambah is listed at the Heritage Branch website..........The original grantee, George Cobb's daughter Mary, married Francis White of Edinglassie in 1853 and 4 of their children were born at Anambah (in the earlier house.) These children later established Belltrees at Scone.
The Mackay family bought both Anambah & Minimbah (at Singleton) from the Cobbs in the 1870s & built both the present Anambah and Minimbah houses. They also owned Redleaf House in Woollahra (now Woollahra Council Chambers). The Mackay family are descendants of Duncan Forbes Mackay, Superintendent of Prisons and Public Works in Newcastle in 1827, who settled at Dungog. Various famous people have stayed in the house, including Dame Nellie Melba (c1908) & the Governors the Earl of Dudley & Lord Gowrie. In the 1950s Anambah was the home of Hal Lashwood, one of the greats of Australian radio & during this period radio entertainers such as Roy Rene (Mo) & Jack Davey stayed in the house.
