The barony of Lynn was created from lands inherited about 1204 from Hugh de Morville. It reportedly was first held by Walter de Lynne, who signed the 1296 Ragman Roll. According to Douglas, the family bore the name Lynne long before coming to Ayrshire. If, as Douglas reports however, the family line is Robert de Lynne appearing in 1207 (Perthshire), William de Lynne appearing in 1246 (Perthshire), and Walter de Lynne appearing in 1296 (Ayrshire), one would expect William (or perhaps even Robert), rather than William's son Walter, to be the de Morville heir, first Lord of Lynn in Dalry, and progenitor of the Lynns of that Ilk. In any case, the Lynns held the property from about 1204 until 1532, when they sold it to the Boyds of Kilmarnock. Even then, however, they retained use of 16 acres of the barony or "dominical lands", which acres were "called Burnesyd, Garden and Lyne Knoll in the town and territory of Lyne, bailliary of Cunningham and sheriffdom of Ayr".
