Sir Alexander Seton, 1st Viscount of Kingston (13 March 1620 – 21 October 1691), a Cavalier, was the first dignity Charles II conferred as King.
Alexander was the son of George Seton, 3rd Earl of Winton (1584–1650) by Anna Hay, daughter to Francis Hay, 9th Earl of Erroll (d.1631).
At the early age of twelve, he received King Charles I on a visit to Seton Palace, delivering himself of a Latin oration at the iron gates of the palace in the presence of His Majesty. There and then the King conferred upon him the honour of knighthood, remarking as he did so: "Now, Sir Alexander, see that this does not spoil your school; by the appearance you will be a scholar."
After extensive travels in foreign lands Sir Alexander came home in 1640. But, refusing to sign the Covenant in 1643, he was excommunicated in Tranent Church, and had to flee to France.
Upon returning he was entrusted with important State business by King Charles II, who created him Viscount of Kingston on 14 February 1651 with limitation to the heirs male of his body. His title was taken from a village of that name in Dirleton parish, about two miles south-west of North Berwick. On the day of his creation, Sir Alexander was, with a gallant little garrison, defending Tantallon Castle against Oliver Cromwell who had laid siege to it. Following twelve days and a "battering with grate canon" the defenders were compelled to surrender, but only after quarter had been granted to them in recognition of their bravery.
In 1668 Lord Kingston was appointed, by the King, commander of the Haddingtonshire Militia.
Lord Kingston married four times.
Firstly to Jean Fletcher (d. August 1651), only daughter of Sir George Fletcher, Gentleman of the Privy Chamber in Ordinary to King Charles I, and brother of Sir Andrew Fletcher of Saltoun, a senator of the College of Justice, and had issue:
Kingston married secondly Elizabeth Douglas (30 May 1632, Stoneypath Tower, near Garvald, - Wednesday 21 October 1668, Whittingehame) sister and heir of Archibald Douglas of Whittingehame, and had issue:
Following the death of Elizabeth Douglas, Kingston married Elizabeth Hamilton, daughter of John Hamilton, 1st Lord Belhaven and Stenton. Following her death he married fourthly, Lady Margaret Douglas, daughter of Archibald Douglas, 1st Earl of Ormond. He had no issue by his last two wives.
Lord Kingston was buried on 25 October 1691, within the parish church of Whittingehame, Haddingtonshire.
Kingston wrote a continuation of his family history which was begun a century earlier by Sir Richard Maitland;
