Document 2: Aulay MacAulay of Ardincaple: Sir Aulay MacAulay of Ardincaple (died 1617) was a Scottish laird, knight, clan chief, and a shire commissioner. He was the son and heir of Walter MacAulay Ardincaple, who was the laird of Ardincaple and chief of Clan MacAulay. The MacAulay estate of Ardincaple was situated in the location of the modern village of Rhu and Helensburgh, which both lie on the eastern shore of the Gare Loch, in Argyll and Bute. As chief of his clan, he entered into a contract with the chief of the MacGregors, pledging service and assistance to their chief. His clan feuded with the Buchanans, and his marriage to the widow of a deceased Galbraith chief brought forth feuding with that clan. He also feuded with the Campbells, particularly the Captain of Carrick. The Campbells made several attempts on his life and he was wounded one such encounter. Towards the end of his life he was knighted for his services. On his death he was succeeded by his first cousin.

Document 4: Scottish clan chief: The Scottish Gaelic word "clann" means children. In early times, and possibly even today, clan members believed themselves to descend from a common ancestor, the founder of the Scottish clan. From its perceived founder a clan takes its name. The clan chief is the representative of this founder and represents the clan as well. In the Scottish clan system, the term chief denotes a greater chief than that of a chieftain. In consequence, branch chiefs (heads of branches of a clan) are designated chieftains. Scottish clans who no longer have a clan chief are referred to as armigerous clans.
