Notes - Evidence for the relationship between Iain Mor Tanistair MacDonnell and his daughter of unknown name shown here as well as the relationship to her husband is not verified and is anecdotal only. Several sources record that James Stewart of Albany married a "Lady MacDonald of Antrim". Her name is never given. "Of Antrim" is reasonably understood to refer to the leading house of Antrim. And this would seem an appropriate and reasonable match for an Albany Stewart fleeing the King's wrath. Some sources identify her as a daughter of the Earl of Antrim. However the Earl of Antrim was not created until 1603. But that later MacDonnell Earl of Antrim was a descendant of this family. So a later commentator mighrt reasonably mistakenly refer to this this family as the "family of the Earl of Antrim" even though it was prior to their appointment to that title.
John Mor MacDonald was Lord of Dunnyveg. He was involved in an ongoing feud with the Campbells of Argyll over shipping access to Ireland and he was murdered by James Campbell in 1427. John was also known as "Iain Mhor Tanister".
