Of territorial origin probably from the town of Berkeley in Gloucestershire, England. Several individuals of the name are found in Scotland in the twelfth century. Walter de Berchelai or Berkelai held the high office of Chamberlain of Scotland in 1165, was present in curia regis at Lanark in that year, and witnessed several charters of William the Lion, etc, (APS., I, p. 86, 87, 94; REA., I, p. 10, 14). Humfridus de Berkeley witnessed a charter by Bishop Turpin of the church of Keteryn, c. 1178—98 (REB., II, 257). Robert de Berchelai also appears as a charter witness between 1189 and 1196, and was present in curia regis at Edinburgh (APS., I, p. 88, 94,388). Fourth in descent from Theobald de Berchelai, who came into Scotland in the reign of David I was Alexander de Berkeley, who married the heiress of Mathers and wrote himself "De Berkeley de Mathers" (Angus, II, p. 144). Walter de Berkelay and Robert de Berkelay witnessed William the Lion's grant of burgh and market to the church of Glasgow c. 1175 (REG., p. 37). Dr. Hay Fleming in his introduction to the St. Andrews Kirk Session Register, says: "A witness named Barclay is mentioned four times, and on each occasion his name is spelt in a different way, Barthlhlat, Barclaytht, Bartclaytht, Barclaitht. Judging from the clerk's attempts to take down his name this witness probably lisped" (p. CV). The Barclays possessed considerable estates in various parts of Aberdeenshire and Banffshire, and were hereditary sheriffs of the latter county. They are also found settled in Ayrshire in beginning of the fifteenth century.
