 The House of Lords refused to accept the claim of either James Makgill or Christian Makgill's son, William Maitland.As a result, the title became dormant although Christian's younger sister, Henrietta, later assumed the title of Viscountess of Oxfuird but without establishing the legal right to the title and she died in 1758 without issue.The Nether-Rankeillor estates later passed through an heiress to Frederick Maitland, sixth son of the Earl of Lauderdale.
