Pittonachy, Rosehaugh and Scatwell

Avoch was in the control of David Chalmers, Lord Ormond from 1560/61 but he forfeited his castle and control of Avoch in 1568 when he was exiled due to his part in assisting the escape of Mary Queen of Scots. The castle and village then passed to Andrew Munro of Milntown.^[7] In the late 16th century the Munro of Pittonachy family held the estate of Pittonachy in the parish until Hugh Munro, III of Pittonachy (d.1670) sold it. It then became a property of the Mackenzies who renamed it Rosehaugh.^[8][9] George Mackenzie of Rosehaugh was the first of his family to hold the estate. He was succeeded by his son, also called George Mackenzie, who left an only daughter who died without issue and thus the Mackenzie of Rosehaugh branch became extinct in the male line.^[10] In 1688, the estate was purchased from Mackenzie of Rosehaugh by Sir Kenneth Mackenzie, IV of Scatwell, a family originally from the parish of Contin. Kenneth's son, Roderick Mackenzie, built a new mansion called Rosehaugh House, although in Alexander Mackenzie's 19th century history it was still referred to by the old Munro name of "Pittonachty" (Pittonachy).^[11] This mansion was demolished in 1959.^[12][13]

Mackenzie of Scatwell who owned the estate during the Jacobite rising of 1745 refused to raise his men for the Jacobite cause despite being threatened with military execution by the Jacobite George Mackenzie, 3rd Earl of Cromartie. Scatwell was apparently happy that Cromartie therefore did not return from his expedition to Sutherland.^[14]

Royston

The other estate in the parish of Avoch was the Royston Estate which was owned by James Mackenzie, Lord Royston (died 1744) who was the fourth son of George Mackenzie, 1st Earl of Cromartie (died 1714). James Mackenzie, Lord Royston married Elizabeth, daughter of Sir George Mackenzie of Rosehaugh but their only son, George, predeceased him. When James Mackenzie, Lord Royston died in 1744 he was survived by two daughters, Anne who married but without issue and Elizabeth who married Sir John Stewart of Grandtully with issue.^[15] According to contemporary documents, the Royston estate rental records of Avoch, in 1747 the estate was then held by Lord Royston's grandson, John Stewart.^[16] In 1826, the dormant male Baronetcy of Royston was assumed by a descendant of the Mackenzies of Cromarty and Tarbat, Lieutenant-Colonel Alexander Mackenzie. He died in 1841 without issue and so was succeeded by his younger brother, Sir James Sutherland Mackenzie, who also died unmarried in 1858 and the Baronetcy of Royston became dormant again. Upon his death the baronetcy should have gone to his cousin John Mackenzie, but he did not assume the title.^[17]
