By Margaret Mackenzie of Findon Kenneth had issue -
1. Alexander, his heir and successor.
2. George, who became a merchant in Glasgow, and died unmarried in 1739.
3. Barbara, who, in 1729, married George Beattie, a merchant in Montrose, without issue.
4. Margaret, who died young in 1704.
5. Anne, who, in 1728, married, during his father's life-time, Murdo Mackenzie, VII. of Achilty, without issue.
6. Katharine, who died young.
Sir Kenneth had also a natural daughter, Margaret, who married, in 1723, Donald Macdonald, younger of Cuidreach. Sir Kenneth's widow, about a year after his decease, married Bayne of Tulloch. Notwithstanding the money that Sir Kenneth received with her, he died deeply in debt, and left his children insufficiently provided for. George and Barbara were at first maintained by their mother, and afterwards by Colin of Findon who had married their grandmother, widow of Sir Roderick Mackenzie of Findon, while Alexander and Anne were in even a worse plight.
He died in December 1703, at the early age of 32; was buried in
Gairloch, and succeeded by his eldest son,
IX. SIR ALEXANDER MACKENZIE, the second Baronet, a child only three and a half years old. His prospects were certainly not enviable, he and his sister Anne having had for a time, for actual want of means, to be "settled in tenants' houses." The rental of Gairloch and Glasletter at his father's death only amounted to 5954 merks, and his other estates in the Low Country were settled on his mother, Sir Kenneth's widow, for life while he was left with debts due amounting to 66,674 merks, equal to eleven years rental of the whole estates. During his minority, however, the large sum of 51,200 merks was paid off, in addition to 27,635 in name of interest on the original debt; and consequently very little was left for his education. In 1708 he, along with his brother and sisters, were taken to the factor's house - Colin Mackenzie of Findon - where they remained for four years, and received the rudiments of their education from a young man, Simon Urquhart. In 1712 they were all sent to school at Chanonry, under Urquhart's charge, where Sir Alexander remained for six years, after which, having arrived at 18 years of age, he went to complete his education in Edinburgh. He afterwards made a tour of travel, and returning home in 1730 married his cousin, Janet Mackenzie of Scatwell, on which occasion a fine Gaelic poem was composed in her praise by John Mackay, the famous blind piper and poet of Gairloch, whose daughter became the mother of William Ross, a Gaelic bard even more celebrated than the blind piper himself. If we believe her eulogist the lady possessed all the virtues of mind and body but in spite of all these graces the marriage did not turn out a happy one; for, in 1758, she separated from her husband on the grounds of incompatibility of temper, after which she lived alone at Kinkell.
