Aulay MacAulay of Ardincaple was the last known Chief of Clan MacAulay. In the mid eighteenth century he was in dire debt, sold Ardincaple, and died in poverty in 1767. He had no children and did not appoint a tanist. He had relatives of course, but to inherit the title they would also have had to agree to inherit the debts that then went with it.
One *Alexander MacAulay of Dublin is on record as having refused to do so. The MacAulay's own sister was married to one of his debtors, and as women can inherit titles under Scottish law, his brother-in-law could have taken on and claimed the Chiefship. But no claim was made, so all the lines that were approached in this way disqualified themselves, having refused the title.
