In the Public Record Office book "Exchequer Rolls of Scotland" Vol. IV, 1406 - 1436 page 327 there is an entry -
"Compotum Willelmi Nigelli et Patricii Ahaire, ballivorum burgi de Are, (Perth, 17 July 1420, from Whitsunday 1418 to Whitsunday 1420 exclusive : 4 terms. Fermes, by feu-charter, 40 pounds; paid, as p. 22, to Dominicans of Ayr, by receipt of their Prior.)
I wonder if there was a mistake in the transcription or a typographical error - Ahaire instead of Adaire ?
