XII. Walter Dennistoun (as the name is generally spelt from this time) of Colgrain, on his marriage with Sarah, daughter of Sir Patrick Houston of that Ilk, by Lady Janet Cunningham, 19th December, 1605, was vested by his father in the fee of his lands of Colgrain, two Camis-Eskans, Auchindennan, and Cameron. She brought him a tocher of 6,000 merks, and by his marriage contract he interdicted himself to Sir James Edmondstone of Duntreath, John Houston of that Ilk, Alexander Cunningham of Craigends, and Robert Sempill of Fulwood. He was infeft 12th April, 1610, in the lands of North and South Kipperminshock, upon a Crown charter, which narrated the immemorial possession of his ancestors therein as "nativi tenantes, rentallatores, et predecessores," in terms of statute 1594, c. 218, by which the production of resignations or precepts of sasine by possession infeft for forty years, is dispensed with. The debts accumulated by his father and grandfather pressed heavily upon Walter, and forced him to alienate several considerable portions of his paternal estate. He resigned the Kipperminshocks in favour of William Hall in 1611, and in 1612, the lands of Cameron were comprised by Alexander Colquhoun of Luss, for the sum of 5,000 pounds Scots. As we do not any longer find the lairds of Colgrain making up titles to Auchindennan, it was probably sold about the same time. He purchased from John Wood of Geilston the lands of Kirkmichael-Stirling, for which he had a charter of confirmation from Sir Archibald Stirling of Keir, 21st December, 1621. Walter Dennistoun, on 9th April, 1623, took for his second wife, Grizel, daughter of John Brisbane of that Ilk, by Anna, daughter of Blair of Blair, and conveyed to her the lands of Colgrain and Kirkmichael-Stirling in liferent. He died about 1640, and left two sons
1. John, who succeeded him.
2. James, who, on the death of his brother without heirs male, became representative of the family, but died without issue.
1. Janet, who married Mr. David Elphinstoun, minister at Dunbarton, with a tocher of 2,000 merks. She was probably by the second marriage, and died before 1656, leaving a daughter, Janet.
