[1] He was on good terms with his stepsons, Alexander Gordon, who stayed at Innerpeffray in 1544 and 1548, and the Earl of Huntly.
[3] On 16 May 1554, Robert Elphinstone, 3rd Lord Elphinstone put his affairs in the hands of his father-in-law Lord Erskine, John Drummond of Innerpeffray, and his brothers-in-law Robert Drummond of Carnock and John Hamilton of Haggs, because he had made poor decisions about his properties in his youth.
This transaction was enacted before Mary of Guise and the Privy Council of Scotland in her presence chamber at Stirling Castle.
[4] John Drummond died in February 1560 and was buried in the chapel his family built at Innerpeffray.
A group of nine carved oak panels, which include John Drummond and Margaret Stewart's heraldry are held and displayed by the National Museums of Scotland.
