Alexander was succeeded by his son, Ranald, the 18th Chief, followed by his son, Richard (19th Chief). The chiefship would become dormant in 1848 with the death of Chichester, the 21st Chief. The next chief wasn't acknowledged until 13 September 2006 when Ranald Alasdair MacDonald of Keppoch was acknowledged as the lawful chief by the Lyon Court, following a 30-year fight for the right to use the ancient title of "Mac Mhic Raonuill". His descent from Donald Gorm, younger brother of Archibald 15th Chief (c. 1680) was accepted by the Court.
