(A branch off Lockharts of Lee)
by Isabelle S. Lockhart
The barony of Castlehill in Lanarkshire, Scotland was formed out of a portion of the lands of Lee, which Sir James William LOCKHART (b.1596-d.1674), 12th of Lee 1630, bestowed on his third son, John. [The Upper Ward of Lanarkshire]
The lands of Cambusnethan were sold to the Lockharts of Castlehill, in favor of James Lockhart of Castlehill (b.1677-d.1696) (12th Baron). The lands were incorporated into a free barony, called the Barony of Cambusnethan by a charter under the Great Seal, dated 26 July 1695. The proprietor of the barony of Cambusnethan is always to assume the name of Lockhart. [The New Statistical Account of Scotland, 1845, p.613]
The superiorities of the estates in the parish of Stonehouse, were also formed into a barony by a charter under the Great Seal called the Barony of Castlehill, which is the title that the family of Cambusnethan retained. [The New Statistical Account of Scotland, 1845, p.613]
