In 1522, the 16-acre mains of the barony of Lynn were conveyed in a charter from John Lyne of that Ilk to John Lyne of Bourtreehill, described therein as the "... dominical lands of Lyne called Burnesyd, with a house, garden, and Lyne Knoll." In 1532, John Lyn "for a sum of money to him paid, sold" to Thomas Boyd a portion of Lyn ("forty-shilling land of old extent", the latter term referring to a former valuation). Nevertheless, the Lynns continued to hold the 16-acre mains of the property: in 1583, the mains were conveyed by Laurence Lyn (of Bourtreehill) to William Lyn, his son and heir apparent; on this occasion, the mains were further described as "... dominical lands of Lyne together with the house called Burnesyd with the garden thereof and Lyne Knoll "lying in the town and territory of Lyne bailliary of Cunningham and sheriffdom of Ayr"" (emphasis added).
