The Abernethy barony was passed down to Sir Hugh's son Alexander who was an avid supporter of the fight to maintain Scotland’s independence from England. When Edward I became King of England Alexander changed his views and became a supporter of the English. For this he was appointed the warden of the area between the Firth of Forth and the Highlands. Alexander, under the order of King Edward II, was sent to Rome to gain the favor of the Pope against the Scots. It was a failed attempt. Scotland’s King Robert Bruce then declared all of Alexander’s lands to be forfeited due to Alexander’s disloyalty. And, since Alexander had no male heir, all of his holdings went to his three daughters Margaret, Helen, and Mary. Margaret married the Earl of Angus. Helen married the Earl of Crawford, and Mary married the 6th Baron of Leslie, Sir Andrew. With the marriage of Sir Andrew and Mary Abernethy the Leslie’s acquired the baronies of Ballinbreich and Caimey, which were some of the most important of the Abernethy estates. Also, Clan Leslie gained Abernethy and Cairney as septs to the Clan. The third son of the marriage of Sir Andrew and Mary was John. John was the direct ancestor to the Earl of Rothes.
