Hector Roy received a grant of Gairloch from King James IV. in 1494. He is believed to have had a similar grant some years before.
Several of the dates given above are conjectural, especially among the earlier generations. For fuller details and evidence of dates see the History of the Mackenzies by Alexander Mackenzie, F.S.A. Scot.
Since John Roy Mackenzie, each laird of Gairloch has been the eldest or eldest surviving son of the preceding laird. John Roy was third son of John Glassich, who was the eldest son of Hector Roy. John Roy’s elder brothers, Hector and Alexander, died without issue.
