Patrick Gray, 4th Lord Gray (c. 1518 -1584) was a Scottish landowner and Sheriff of Angus, active during the war of the Rough Wooing as a supporter of the Scottish Reformation.
Patrick Gray was the son of Egidia Mercer and Gilbert Gray of Buttergask half-brother of Patrick Gray, 3rd Lord Gray, and the grandson of Andrew Gray, 2nd Lord Gray. He became Lord Gray in April 1541 after the death of his uncle. In order to succeed to the Gray lands as heir of his grandfather he had to pay 10,000 marks to James V's treasury, and was confirmed Lord Gray on 14 September 1542. He was still paying Regent Arran in 1543.
Patrick Gray married Marion Ogilvy in 1537. Their son was Patrick Gray, 5th Lord Gray. Patrick was married again to Margaret Ker, daughter of Sir Walter Ker of Cessford, in 1557. The chief residence of the Grays was Fowlis Castle in the Carse of Gowrie, and they lived at Castle Huntly near Dundee. In 1583, an English list of the Scottish nobility described Patrick with an interesting but inaccurate English pedigree;
"an aged man, esteemed to come of English bloode, that came into Scotlande with the Lady Somerset, wyef to King James the Firste. In religion suspected; of no greate power or frendes. His eldest sonne married th'erle of Gowrie's father's sister, and his other the daughter of Lord Glamis."
Lord Gray was captured by the English at the Battle of Solway Moss and was held by the Archbishop of York. When he returned to Scotland he made a band of friendship or 'manrent' with Cardinal David Beaton at St Andrews on 22 October 1544.
On 11 March 1547, during the siege at St Andrews Castle, Gray made a pledge to Edward VI of England. This contract stated that for English assistance in re-instating his rights over Perth, and the return of his brother, who was a hostage (called a "pledge" in the language of the time) in England; Patrick Gray would further the marriage of Mary, Queen of Scots to Edward VI, and deliver Broughty Castle and the Spey Tower at Perth to the English army. This instrument was witnessed by Norman Leslie, James Kirkcaldy of Grange, Henry Balnaves, and Alexander Whitelaw of Newgrange.
Gray asked to be compensated for his fishing rights at Broughty; he was duly paid £1000 on 14 November 1547 by Sir Andrew Dudley, an English soldier and brother of the Duke of Northumberland. At the same time, the Master of Ruthven, whose father was Provost of Perth and Gray's rival, offered to deliver Perth to the English. In June 1548, Thomas Fisher brought him the Lord Protector's thanks, a gold chain, a pension of 1000 crowns and a gift of 300 crowns. Gray was captured by French troops in November 1548 and summoned for treason on 18 December 1548. D'Essé, the French commander, wanted him executed, but Regent Arran and the other Scottish lords protested.
During the crisis of the Scottish Reformation, Mary of Guise wrote to Lord Gray on 11 May 1560 to inform him of the defeat of an English assault at the Siege of Leith. In August 1560, Lord Gray attended the Scottish Reformation Parliament, and signed the commission for the marriage of James Hamilton, 3rd Earl of Arran to Elizabeth I of England, (which had no effect). Some years before, Gray had been captured by the English at a border incident called the Raid of Swinton. In 1562 he was detained in England, on account of his old bail conditions – he had been, "lattin hame upoun ane band." Mary, Queen of Scots, wrote to Elizabeth to complain at his ill-treatment.
