In 1593, James VI was linked with another member of the Lyon family, Euphemia Douglas, daughter of Sir William Douglas of Lochleven, Earl of Morton and Agnes Leslie. She married the Master of Glamis in 1586. She and her sisters were sometimes called the "seven pearls of Lochleven", and she may also have been known as "Lady Glamis". Dr Tobias Matthew, Bishop of Durham wrote of the "king's affection to the Lady Morton's daughter", and that she might be connected with the Earl of Bothwell's schemes, and draw a person of "greater estate" into Elizabeth's devotion. In a second letter Matthew mentioned a mystery concerning the "king's love" Lady Morton's daughter and letter intercepted by Bothwell concerning the succession to the English throne intended for the person of "great estate". Euphemia Douglas however, was not the king's mistress mentioned in Carey's letters. Matthew's story may concern another of the seven Douglas of Lochleven sisters.
