[1] A letter from an English soldier at Berwick denouncing a Captain Carey in 1588 claimed that he frequently allowed Hercules Stewart and the Earl of Bothwell access to the garrison town.
[3] In March 1592 he was thought to be in hiding in Northumberland with the earl, the younger Laird of Niddry, and others who had tried to access the king's presence by force at Holyroodhouse.
They withdrew to Niddrie where, on 5 April 1594 Hercules Stewart was given command of a section of Bothwell's troops and fought and defeated the king's soldiers under the Master of Glamis and the Earl of Home, who split into two groups and retreated towards Edinburgh Castle and Holyroodhouse.
[9] Hercules and Josias Stewart was interrogated and revealed information about a band or league between Bothwell and the Catholic rebel Northern earls.
In 1620, a French woman, Jacqueline Quenlie, petitioned the Privy Council of Scotland that John Hamilton of Ferguslie was her husband in Ireland, and he had married Margaret Stewart unlawfully and taken two coffers of her belongings to Paisley.
