 The 8th baron is the current chief of the name and arms of "Macdonald" and high chief of Clan Donald.The current chiefs of Clan Donald and Clan Macdonald of Sleat both descend from the 3rd baron (Macdonald of Macdonald from his second son; Macdonald of Sleat from his eldest son).This reason for this is because the 3rd baron's eldest son, Alexander William Robert Macdonald, was considered to be illegitimate under English Law.
