Also, even though the heraldry of the Macleod of The Lewes is very different from that of the Macleod of Macleod, there may be a connection with the Hebridean Nicolsons/MacNicols. In their coat of arms, the Macleods of The Lewes have โa black burning mountain on a gold fieldโ. According to Sellar, when the Macleods married the Nicolson heiress of tradition, her arms would have likely passed to the Macleods as well. The Hebridean Nicolsons/MacNicols were supposed to have held their lands in the Western Isles from the Norse rulers for their services as coast-watchers, hence the burning mountain on the arms of Macleod of The Lewes.
