William Murray, Marquess of Tullibardine (1689-1746), eldest surviving son of the 1st Duke of Atholl and brother of Jacobite Lieutenant-General Lord George Murray, had been heavily involved in the risings of 1715 (following which he was attainted for treason) and 1719. He spent the following years in exile in France, suffering from poor health and relative poverty, despite secret financial support from his family in Scotland.
