SIR JOHN SETON OF BARNES, the third son of George, 7th Lord Seton, resided for some years at the Court of Philip II., of Spain. Viscount Kingston in his historical account of the Seton family says that Sir John ‘was a brave young man,’ and that he was made by King Philip 'Knight of the Royal Order of St. Jago', 'att that tyme the only order of knighthood in that kingdome of greatest esteem; in memory whereof he and his heirs has a sword in their coat of armes, being the badge of that order. King Philip also preferred him to be a gentleman of his chamber and Cavalier de la Boca (Master of the Household). He also carried the golden key at his syde on a blew ribbing, all which were the greatest honours King Philip of Spain could give to any of his subjects, except to be made a grandee of Spain. He had a pension granted to him and his heirs of two thousand crowns yearly.'  Sir John Seton was recalled to Scotland by James VI, who made him Lord Treasurer, Master of the Horse, and an Extraordinary Lord of Session sitting as Lord Barnes (taking the place of his brother Alexander who was promoted to President of the Court of Session).  His son, Sir John Seton, 2nd of Barnes, was an officer of the Court of King Charles I.  The Seton of Barnes family became the heirs of the Earldom of Dunfermline, though the estates having long since been forfeit.
