A number of Nicolsons were involved in the covert activity that surrounded the sheltering of the fugitive Prince Charles Edward in the Hebrides after Culloden. As a cousin of the intensely Jacobite MacLeods of Rassay, the chief, John Nicolson, appears to have assisted in the concealment of the prince in a cow byre on his estates: John's descendants preserved a lock of the prince's hair, and the cup out of which he drank on his night on Scorrybreac lands. Margaret Nicolson, grand-daughter of Reverend Donald, and wife to John MacDonald of Kirkibost, North Uist, crossed the Minch to Skye to inform the prince's supporters of his imminent arrival in the company of Flora MacDonald. Another man of the clan, Donald Nicolson from Raasay, also helped to protect the Young Pretender during his flight, and was recorded by Bishop Robert Forbes in "The Lyon in Mourning" as suffering torture for his refusal to reveal the whereabouts of the prince after arrest by government troops. Donald Nicolson's descendants emigrated to Australia, and recorded the memory of his service as one of the prince's guides in their family Bible. Alexander Mackenzie, in his history of Clan Mackenzie, claims that Angus Nicolson of Stornoway raised 300 men from the Isle of Lewis for Jacobite service, only to be ordered back by a furious Earl of Seaforth when they landed on the mainland.
