1588, upon the death of Archibald Douglas, 5th Earl of Morton, Sir William became the 6th Earl of Morton. From that time onward Agnes was styled the Countess of Morton. Sir William received the charter for the earldom on 20 July 1589. She was one of 8 "dames of honour" appointed to attend Prince Henry at Stirling Castle in 1594. Sir Robert Cecil noted in 1599 that her husband was retired from politics, but Agnes Leslie was still a "great practicer", and in the confidence of Anne of Denmark. Agnes died sometime around the year 1606, which was the same year her husband died.
