 In 1456 Lachlan's son, "Donaldus Maclachlane dominus de Ardlawan" ("Ardlachlan", or Castle Lachlan), like his ancestor Gillespie, granted the Preaching Friars of Glasgow six shillings and eight pence per year, from the same pennylands of Killbride beside his home Castle Lachlan.One tradition of the Maclachlan lairds was thought to date from the era of the Crusades.The tradition was that the laird of Strathlachlan (Maclachlan of Strathlachlan) and the laird of Strachur (Campbell of Strachur) would attend the funerals of each other and "lay his neighbour's head in the grave".
