Background
Mackenzie was born on 13 May 1842, at the Chateau de Talhouet, near Quimperlé, in Morbihan, Brittany. His father was Sir Francis Mackenzie, 5th Baronet and 12th laird of Gairloch. The Mackenzies were a clan from the Northwest Highlands that had risen to prominence in the 15th century during the disintegration of the Lordship of the Isles.
Mackenzie’s ancestor, Hector Roy Mackenzie, had acquired the lands of Gairloch towards the end of the 15th century.
Mackenzie’s mother, Mary, was the daughter of Osgood Hanbury, of Holfield Grange, Essex.
Education
He was educated at home, in the tradition of his family, and brought up to speak both English and Gaelic.
Career
Mackenzie’s father died a year or so after he was born. In 1862, with the help of his mother he purchased the 12,000-acre (49 km2) estate of Inverewe and Kernsary. There he built a Scottish Baronial style mansion and set about creating a garden.
Mackenzie concentrated first on establishing shelter belts of Native and Scandinavian pines and built a walled garden.
He also created woodland walks. Within 40 years, he had established one of the finest collections in Scotland of temperate plants from both Northern and Southern hemispheres.
Mackenzie wrote a volume of memoirs (published by Edwin Arnold in London in 1921), entitled A Hundred Years in the Highlands. On 26 June 1877, Mackenzie married Minna Amy, the daughter of Sir Thomas Edwards-Moss, 1st Baronet.
They had one child, Mary (Mairi) Thyra, who married first (18 April 1907) Robert John Hanbury (died 5 April 1933) and secondly (2 July 1935) Captain Ronald Sawyer (died 25 October 1945).
She died in July 1953. Mackenzie died on 15 April 1922. She gave the garden to the National Trust for Scotland in 1952, together with an endowment for its future upkeep.
