the youngest of the seven sons. The Lord Advocate, Sir James Steuart of Goodtrees, was his grandfather; his father, also Sir James Steuart, was the eldest son of the Lord Advocate, and rose to be Solicitor General for Scotland. Titles The 3rd Baronet of Goodtrees, the subject of this article, inherited his baronetcy and estates at the age of fourteen. He eventually acquired much of the possession of his cousins, the senior line of Steuarts. Sir Thomas Steuart of Coltness, had married twice: to Margaret Elliot, his step-mother's daughter, and then to Susan Denham, the sister of Sir William Denham, 1st Baronet of Westshield, Master of the Mint for Scotland, and had fourteen sons by them. His eldest son had sold the estate and mansion (but not the title) of Coltness to 3rd Baronet of Goodtrees' father, in 1712. The 3rd Baronet of Goodtrees is, therefore, often called of Coltness, since it was his house. The 3rd Baronet of Goodtrees, however, eventually sold the estate of Goodtrees after he returned from France. By that time, the last surviving son of Sir Thomas Steuart had inherited the Coltness baronetcy from his father as well as the property and baronetcy of Denham of Westshield through his mother, styling himself Sir Archibald Steuart Denham, Baronet. When Sir Archibald died, in 1773, the baronetcy of Coltness, and the Steuart property, passed to Sir James Steuart; the Denham title and property passed to the last heir of the Denhams, Sir Archibald's half-nephew on his mother's side, who took the style of Sir William Lockhart Denham. When he died, three years later, in 1776, the Denham baronetcy became extinct; he also left his property, including the estate of Westshield, to Sir James Steuart, who then assumed the name of Denham, although he was not descended from. For the last four years of his life, therefore, he was Sir James Steuart Denham, Baronet, of Coltness and Westshield. His major book and his posthumous collected works were published as by Sir James Steuart; economic literature also calls him Sir James Steuart Denham. Works In 1767 Steuart published An Inquiry into the Principles of Political Economy, the first book by a Scottish economist with 'political economy' in the title, explaining usage of the term as that: [just as] economy in general [is] the art of providing for all the wants of a family, [so the science of political economy]
