Angus MacDonald Lockhart, the head of the Lockhart clan, passed away with his family by his side at his Lanarkshire estate.
His published will has revealed he ordered his £17,758,874 estate be passed to his family although he did gift £1,000 to Asthma UK.
The estate includes land, castles, other property interests and a stocks and shares portfolio.
Lockhart left several cash legacies to close family but instructed the bulk of his fortune be kept in trust for his wife Susan and children Ranald and Fiona.
He passed away in November last year after falling ill at home aged 69.
An announcement on the Clan Lockhart website read: “Angus died unexpectedly at home with his wife, Su at his side. Following a private family cremation a service of thanksgiving for his life was held at Biggar Kirk on 3 December.
“His ashes will be scattered on the estate. His son, Ranald, succeeds him as Chief of the Clan Lockhart.”
The Lockhart Clan saw Symon, Second of Lee, among knights led by Sir James Douglas who took Bruce’s heart to the Crusades in 1329 to atone for his murder of John Comyn in the church of Greyfriars.
