Sir Thomas Burnett, 3rd Baronet

Sir Thomas was a Commissioner to the Scottish Parliament for Kincardineshire between 1689 and 1707. In 1689 he subscribed to the Act declatory of the legality of the Meeting of Estates summoned by the Prince of Orange, and was a signatory to the letter of congratulation him as King William II. In 1690 he was one of nine appointed to a Parliamentary Committee for the Plantation of Kirks and valuation of teinds, and one of four chosen as Lord Clerk Register. On the discovery of plots for the King's assassination, he was one of the signatories to the association in defence of King William.

He opposed the proposal of making an addition to the standing army, which parliament adopted; and in the same parliament, during the discussions regarding the colony of New Caledonia in Darién Province, when the question was raised whether the company's right should be made the subject of an address to the King or of an Act of Parliament, and the former alternative was carried by a majority of 108 to 84. Sir Thomas Burnett was one of the dissenters and protestors.

In May 1701 he was nominated, with others, for a peerage, but the King, being at the time ill, did not sign the patents, which subsequently lapsed. In 1703 Sir Thomas made a protest against the Act allowing the importation of French wines and brandies as "dishonourable to Her Majesty, and inconsistent with the Grand Alliance in which she is engaged." His votes recorded in connexion with the Union are in favour of the first article and of the whole measure as carried.

On 13 February 1707 he was elected as a Member of the Parliament of Great Britain at Westminster, but he seems never to have presented his commission or taken his seat. On 21 May he was appointed a member of the Privy Council of Scotland, and in July appointed to the Scottish Court of Exchequer.

In his private life he was engaged in an unpleasant dispute, from 1695 to 1702, with the Earl of Sutherland regarding the affairs of the Arbuthnot family. The matter became very acrimonious and finally went to the Court of Session, the legal proceedings being reported upon by Sir John Lauder, Lord Fountainhall.

He married while still under age, in 1677, Margaret (1662–1744), daughter of Robert Arbuthnot, 2nd Viscount Arbuthnot, by his spouse Elizabeth, daughter of William Keith, 7th Earl Marischal. They had sixteen (or even more) children.
