About Dugald Stuart, Lord Blairhall
"Second son of Sir Dugald Stewart of Bute, and of Elizabeth, daughter of Sir Thomas Ruthven of Dunglas, was admitted an advocate on the 30th Nov. 1694. He represented the burgh of Rothsay in Parliament, from 1703 to 1707, and opposed the Union. He was chosen to represent the counties of Perth and Bute in Parliament at the general election in 1708; a petition was presented against his return for Perth, but he sat for both counties till his elevation to the bench in the Court of Session, which took place in 1709, when his uncle Sir Robert Stewart of Tillicutrie, resigned his offices in his favour; and he took his seat as an Ordinary Lord, and also as a Lord of Justiciary, on the 7th of June that year...
...He died at Blairhall on the 16th of June 1712, leaving, says Douglas a high character for honour integrity and ability. His Lordship is supposed to have had the chief hand in the composition of the Memoirs commonly ascribed to Lockhart of Carnwath. His coadjutors are said to have been Mr Lockhart and his chaplain, Mr Gullan, Mr Houston, and Mr Dundas of Arniston."
