The ironworks at Letterewe were commenced about 1607 by Sir George Hay; they were on the property of Lord Mackenzie of Kintail. The iron-smelting furnace at Talladale was most likely established by Sir George Hay about the same time. No doubt woods on John Roy's Gairloch estate were cut down to provide charcoal for smelting, and if so John Roy must have derived pecuniary benefit from the Talladale ironworks, but there is no record to confirm this conjecture. John Roy resided in Eilean Ruaridh, on Loch Maree. There are two islands of the name, distinguished as big and little; they almost adjoin. It was in the little island that John Roy dwelt, in the house where formerly Ruaridh M'Leod had lived. John Roy enlarged and improved the house, and made it his Gairloch home. Some remains of the house and adjoining garden are still to be seen. It was early in 1609 that John Roy paid a visit to the laird of Mackay in Sutherlandshire. On his return journey the laird of Mackay escorted him as far as the Meikle Ferry, on the Kyle of Sutherland. When the party arrived at the ferry, the groom of a gentleman, who was also about to cross, endeavoured to keep possession of the boat. Amongst the attendants of the laird of Mackay was his youthful piper, named Roderick Mackay, a fine lad of seventeen summers. The groom placed his hand on the boat to hold it until his master should come up. The hot-headed young piper drew his dirk and cut off the groom's hand. The laird of Mackay said, "Rorie, I cannot keep you longer; you must leave the country." John Roy Mackenzie said to the piper, "Will you come with me, Rorie?" The piper lad was only too glad to accept this invitation, and his master, who had a great liking for the handsome and talented boy, was quite willing that he should go with John Roy, who sent Hugh Mackenzie of Gairloch, his gamekeeper, to the laird of Mackay in exchange for the piper. The descendants of Hugh Mackenzie still dwell in Sutherlandshire, where it is remembered how their ancestor came from Gairloch. Donald Mor Mackay, an elder brother of Rorie the piper, spent a number of years in Gairloch, and assisted his brother in the office of piper.
