  1. Margaret Boyd, Lady Montgomerie was born 1392 in of Kilmarnock, Ayr, Scotland, and died 1460 in of Eaglesham, Renfrew, Sotland. {n.b. date of birth: double check}
  2. Sir Thomas Boyd, 5th Baron of Kilmarnock was born abt 1405, of Kilmarnock, co. Ayr, Scotland, and died 9 Jul 1439 in Craignaught Hill, Renfrew, Scotland, Scotland.
  3. William Boyd, Abbot of Kilwinning, was born ABT 1407 in Kilmarnock, Renfrew, Scotland [1]


Sir Thomas Boyd was "a man of distinguished abilities who made a great figure during the reign of King James I." He was one of the sureties, or hostages, for the ransom of King James I in 1423 along with Sir John Montgomerie of Eaglesham and Eglinton (usually designed "of Ardrossan").

In 1406 James Stewart became heir to the throne of Scotland, but was unable to claim it for nineteen years as he was held prisoner by the English in the Tower of London. The King was released by the English on the promise of the Scots to pay a ransom of 40,000 pounds. He then ascended the throne in 1424. Sir Thomas was one of the hostages handed over to the English as security for the payment.

Sir Thomas was delivered May 28, 1424, and was released July 16, 1425. He was probably compelled to pay his own ransom. At the time he was delivered as hostage, his annual income was estimated at 500 marks.

He was confined in Dover Castle, being sent there from Fotheringay, and later exchanged at York Castle 16 June 1425. The King was released on the promise of the Scots to pay a ransom of 40,000 pounds, which was never made. The King wasted the money that was raised for it and the many hostages held in the English prisons.

Whether Sir Thomas ever returned home alive we do not know. He was buried with his wife in the old kirk at Kilmarnock, their tomb bearing the inscription:

Hic jacte Thomas Boyde, Dominus de Kilmarnock. Qui ojijt septison die mensis Julii 1432. Et Johanna de Montgomerie eius spouce Orate pro iis

The old kirk collapsed in 1800, and was replaced by the present Laigh Kirk. [580,5565]




[1] William, Abbot of Kilwinning, obtained from King James III a charter confirming grants of the Crown to the Abbey. William had a dispensation from Rome, and received grants of land in Lanarkshire. These descended in lineal succession until sold by the late Reverend William Boyd, D. D., father of the Edward Boyd of Mertin's Hall, County of Wigton, Scotland. Their Arms are the same as the Kilmarnock family.
