"The numbering of the Earls from the 3rd onwards needs revision in the light of current interpretation of the Act of 26 May 1826 reversing the Act of Attainder of 13 Nov 1715 against James, Lord Ogilvy. It is now thought that the purpose of the reversal was to restore the Earldom and two subsidiary Scottish Lordships of Parliament held with it retroactively, such interpretation resting as it does on the rider 'as if it had never been' ('it' referring to the Attainder). If so, the James, Lord Ogilvy, already mentioned above, who dsp 12 Jan 1730/1, should be regarded as 4th Earl but for the attainder; his younger brother John (self-styled 4th Earl) should be regarded as 5th Earl but for the attainder; David, self-styled 5th Earl, should be regarded as 6th Earl but for the attainder; the mad David Ogilvy, who died 1812, should be regarded as 7th Earl but for the attainder' the latter's uncle Walter Ogilvy (d. 1819) should be regarded as 8th Earl but for the attainder, and David, immediate beneficiary of the 1826 reversal, should be regarded as 9th Earl but for the attainder; for '5th Earl etc' as regards subsequent Earls of Airlie, read '10th Earl etc.' and so on."
