The present chiefs descend from a younger brother of Aeneas and Gillies MacBean, the two elder sons of William MacBean of Kinchyle. Aeneas had a daughter, so his heir to Kinchyle was his nephew Captain Donald MacBean, son of Gillies, who left two daughters as his heirs. The chiefly line did not continue through any of these daughters, but instead continued through one of Aeneas and Gillies' younger brothers. The copy of the grant of arms of McBain of McBain by The Lord Lyon to Hughston McBain as 21st chief (having succeeded his older cousin Stewart McBain of Glenbain in Saskatchewan) confirms that the line of succession passed via Hughston's great-great-grandfather William McBain of Pittourie, and states: "Which William was great-grandson and eventual Representative of William McBean of Kinchyle, Chief of the Clan McBain". This matriculation was listed in "The Edinburgh Gazette", 27 May 1966.
