Agnes was the daughter of a great father who had fought with King Robert the Bruce at Bannockburn, and in the following decades, continued to make military forays into England. He was a hero. After Bruce’s death, he was Regent of Scotland for a while.
Like her father, Agnes’s husband was in constant combat against the English. If he was on one of his military forays, then it was up to Agnes to manage the castle, and if necessary, to defend it. She was put to the test in 1338, when an English army under the command of the Earl of Salisbury approached, trying to take castle. A castle in which there were hardly any men left, just women and children.
