An agreement was formed between Sir William, abbot, and the convent of Paisley and Hugh, son of Reginald, knight, concerning the controversy called between them over the land that is called ‘Achinchoss’ in feu of the said Hugh, knight, which the abbot and convent claimed to belong to their church of Killellan (RNF). It was decided that Hugh shall hold the land of the house of Paisley, rendering annually 1/2 mark to the monks at Paisley towards the lighting of their church. The monks, for themselves and Roger, vicar of Killellan, and Hugh, for himself and his heirs, agreed that this composition would remain in place in perpetuity. The monks shall warrant the land of ‘Achinchos’ against all vicars of the church of Killellan. If Hugh shall cease from this agreement, he shall pay 1/2 mark penalty. Walter, bishop of Glasgow, confirmed this agreement by episcopal authority.
