Agnes Leslie, Countess of Morton

She was the wife of William Douglas, 6th Earl of Morton, who as Laird of Lochleven Castle was the custodian of Mary, Queen of Scots during her captivity from June 1567 until her escape on 2 May 1568.

Sir William's half-brother from his mother's liaison with the king was James Stewart, Earl of Moray, Regent of Scotland from 1567 until his assassination in January 1570.

The couple made their home at Lochleven Castle, which was a fortress situated on an island in the middle of the loch, and where his widowed mother also resided.

[7] Agnes became the Queen's chief female companion during her ten and a half months of imprisonment, accompanying her throughout the day and often sleeping in her bedchamber.

[13] Sir Robert Cecil noted in 1599 that her husband was retired from politics, but Agnes Leslie was still a "great practicer", and in the confidence of Anne of Denmark.
