The Lands of Lainshaw lie in Strathannick and were part of the Lordship of Stewarton, in East Ayrshire, Scotland. Lainshaw House is a category B listed mansion, lying in a prominent position above the Annick Water and its holm in the Parish of Stewarton, Scotland. Part of the much older Lainshaw Castle is contained within the several later building phases of the present day Lainshaw House.Millar, Page 108 The names 'Langshaw' or 'Langschaw' were used in historic times. Law Mount near the High and Laigh Castleton farms has been suggested as the site of the original castle, granted in the 12th century to Godfrey de Ross by Hugo de Morville.Campbell, Page 212
