Andrew Stuart, 3rd Lord Ochiltree

Andrew Stewart, 1st Baron Castle Stuart (1560–1629) was a Scottish nobleman, soldier, courtier to King James VI and I and one of the chief undertakers in the Ulster Plantation.

Described as 'a nobleman of impeccable background and proven military ability', he was the only son and heir of Andrew Stewart (d.1578), Master of Ochiltree, and Margaret, daughter of his first cousin Henry Stewart, 2nd Lord Methven of Methven Castle. He was the grandson of Andrew Stewart, 2nd Lord Ochiltree, whose title he succeeded to after his father predeceased his grandfather.

He became a General in the Artillery and held the office of General of Edinburgh Castle. He was appointed to the High Court position of First Gentleman of the Bedchamber to James VI and I. On the death of his grandfather in 1591, he became the 3rd Lord Ochiltree and inherited estates in Galloway and Strathclyde. In 1608, he was sent by the King to quell feuds in the Western Isles, taking with him his uncle, John Knox. Though successful in this campaign, the King had no money with which to reward his military service and instead (in 1609) offered him 3,000 acres of land in County Tyrone, which included the Manors of Castlestewart and later Manor Forward, encompassing the area around Farlough and Roughan, all in the Barony of Dungannon. He was one of the chief 'planters' or 'undertakers' in the Ulster Plantation and in 1611 he settled on these estates. He built houses, farmed the land, constructed Roughan Castle and provided housing and employment for the local populace. He lived at Irry, which was later renamed Stuart Hall by his descendants.
