The Clan Montgomery is thought to have originated from a Norman family that held the Castle of Sainte Foy de Montgomery at Lisieux.

The first Montgomery who appears on record in Scotland is Robert, who obtained the lands of Eaglesham in Renfrewshire (south of Glasgow).

John de Montgomery and his brother, like most other clans of that time, are listed on the Ragman Roll, pledging loyalty to Edward I of England for their estates in 1296. It is thought they fought alongside Robert the Bruce in the War of Independence in the early 1300s.

Sir John Montogomery, 7th Baron of Eaglesham, fought at the Battle of Otterburn in 1388, capturing Sir Henry Percy. The Percys paid a large ransom for the release of Sir Henry, money used to help build Polnoon Castle at Eaglesham for the Montgomerys'.

Sir John Montgomery married the heiress of Sir Hugh Eglinton, leading to him gaining the Barony of Eglinton and Ardrossan, an area just north of Irvine in Ayrshire with the original Eglinton Castle from the 1300s.

Alexander Montgomery was a member of the king’s council, sent on several important missions to England. He was awarded the title Lord Montgomery in 1449. https://www.ayrshirescotland.com/clans/montgomery.HTML
