Kenneth Mackenzie, 1st Earl of Seaforth

His paternal grandfather was the attainted William Mackenzie, 5th Earl of Seaforth, whose estates he repurchased from the government.

In June 1781 he sailed with the regiment when it embarked for India, but on 27 August 1781 he died on the journey and was buried at sea.

Mackenzie married first Lady Caroline Stanhope (1747–1767), daughter of William Stanhope, 2nd Earl of Harrington by whom he had one daughter, Lady Caroline Mackenzie (1766–1847), who married Louis Drummond, Comte de Melfort [fr] (d. 1833) and had children.

[6] Sir James Balfour Paul describes her tactfully as "a fashionable beauty of the town",[1] but Horace Bleackley is rather more explicit: The graceful Harriet Powell, equally frail and famous, whose winsome face was portrayed in many a mezzotint, had spent her early youth as an inmate of Mrs Hayes's disreputable establishment in King's Place, but now at last she had become faithful to one man, and was keeping house with Lord Seaforth, the creator of a famous regiment.

[7]Seaforth's biographer has summarised him as: ...a dandy, musician and connoisseur, an adventurer and lady's man, Chief of his Clan, and founding Colonel of his own regiment.
