The first Duke of Atholl's younger son was Lord George Murray, a Jacobite general who was the architect of the early Jacobite successes of the Jacobite rising of 1745. Most military historians concur that if Lord George Murray had been given the sole command of the Jacobite army that the "Old Pretender" (James Francis Edward Stuart) might well have gained his throne. Lord George's elder brother, the next duke, supported the British-Hanoverian Government, and George's half-brother, Lord John Murray, was made Colonel of the 43rd Regiment of Foot (later the 42nd), in April, 1745. As a result, at the Battle of Prestonpans in September, 1745, there were Murray regiments on both sides. Lord George Murray would go on to lead the Jacobite charge at the Battle of Falkirk (1746) and the Battle of Culloden (1746). He died in exile in the Netherlands in 1760.
