Affric taking place in 1721. There exists in the Scottish Register of Tartans a "Glenaffric Fragment" that possibly dates from the late 17th century. Dudley Marjoribanks, later Lord Tweedmouth was a rich Liberal MP who took a long lease on shooting rights over much of Glen Affric in 1846 and, by 1856, had acquired ownership of the Glen Affric Estate from "Laird Fraser" whose family had built the original Guisachan Georgian manor house around 1755. The estate held over at the time of its transference from the Clan Chisholm to Lord Tweedmouth. By the 1860s, Lord Tweedmouth, as the new laird, had much enlarged the house, using Scottish architect Alexander Reid who designed many buildings on Tweedmouth's vast Glen Affric Estate, including an entire village—Tomich—and the Glen Affric Hunting Lodge, described in appearance as "castle-like". Tweedmouth had enjoyed shooting rights over much of Glen Affric since 1846, and, following his acquisition of the estate he initiated the first breed of golden retrievers at kennels near Guisachan House. He put the retrievers to good use at the shooting parties he hosted when at Glen Affric Lodge. The retrievers were sent to other estates when, for some months of the years 1870–71, he leased the Glen Affric Estate to Lord Grosvenor. In 1894 Edward Marjoribanks, 2nd Baron Tweedmouth had inherited the Glenaffric and Guisachan estates from his father. His wife, the Baroness Tweedmouth, was born Lady Fanny Spencer-Churchill, the daughter of the 7th Duke of Marlborough, and died at Glen Affric Lodge in 1904. Known in the highlands as the Lady of Glenaffric and Guisachan, she was reported to be a "lover of the golden retriever dog". The Duke and Duchess of York are reported in The Graphic, 25 September 1897 to have visited the Guisachan Estate in Strathglass, including Glen Affric Lodge. Lady Tweedmouth's nephew Winston Churchill also came to visit the estate in 1901, and amused himself learning how to drive a car in the grounds. Clan Marjoribanks' ownership ended with Edward’s son, Dudley Churchill Marjoribanks, who became 3rd Lord Tweedmouth in 1909. He and his wife had two daughters, but no male heir. For the next few years, until 1918, the estate was owned by the family of Newton Wallop, 6th Earl of Portsmouth (1856–1917). Marmaduke Furness, 1st Viscount Furness owned the estate throughout the 1920s and 30s. The entire property, then consisting of , had been sold by
