Robert Gayre of Gayre and Nigg (original name Robert Gair), the father of the present chief, created the clan after World War II.
He is the chief source for most of the information in the Clan's Wikipedia article, which can be found nowhere else; Robert Gayre invented the Clan and its history.
[2] World Orders of Knighthood and Merit by Guy Stair Sainty (published by Burke's Peerage) refers to "the late Robert Gayre (first Chief of the newly formed Clan Gayre)".
[3] The Glasgow Herald newspaper, on 14 June 1975, wrote, "Robert Gayre, of Gayre and Nigg, is singular among genealogists, dynasts and the like, if only for the reason that, alone among them, he has been able to create a Scottish clan from scratch, providing it with traditions, rituals, precedences and privileges...".
Camp showed that Gayre did not himself have a male-line descent from earlier families of that surname.
