Which historical figure was married to James Hepburn in Scottish history?

Mary, Queen of Scots, is the historical figure who was married to James Hepburn, the 4th Earl of Bothwell. This marriage was highly controversial and took place during a tumultuous period in Scottish history. Mary married Bothwell shortly after the death of her second husband, Henry Stuart, Lord Darnley, which prompted public outcry and accusations that Bothwell had been involved in Darnley's murder. This scandal ultimately led to Mary's abdication and imprisonment, signifying a critical turning point in her life and a significant moment in Scottish political history.

Mary Stuart is another name for Mary, Queen of Scots, which might lead to confusion, but the names refer to the same individual. Elizabeth I, while a significant figure in history, was not connected to James Hepburn in a marital sense, nor was Anne Boleyn, who lived during an earlier time and had no relation to Hepburn. Understanding this context helps clarify why Mary, Queen of Scots was the most accurate answer.
