Mary Bruce

Mary Bruce (c. 1282–1323) was a younger sister of King Robert I of Scots. After her brother claimed the crown in 1306, she was handed to the English by the Earl of Ross. Edward I ordered her displayed in a cage at Roxburgh Castle, where she was held for about four years.

Moved to better confinement in 1310, she was freed in 1314 in exchange for English nobles captured at Bannockburn. She married Sir Neil Campbell.
