Alasdair Mor

Alasdair Mor Mac Domhnaill (Anglicised: Alexander Mor, son of Donald) was a younger son of Domhnall mac Raghnaill—the eponymous ancestor of Clan Donald. He first appears on record in 1253, when it is recorded as witnessing a charter by his brother, Aonghas Mor a Ile, to the Paisley Abbey. According to the 19th century Clan Donald historians Angus and Archibald Macdonald, Alasdair Mor must have been a prominent man as he is the only recorded brother of the Aonghas Mor a Ile. He is recorded in the Annals of Connacht, in the year 1299, as being a man noted for being a "generous and bounteous man". In that year he was slain in a conflict with Alasdair of Argyll and the MacDougalls. According to the traditional shanachies, Alasdair Mor married Amie Ergadia and had at least five sons: Domhnall, Goraidh, Donnchadh, Eoin and Eachann. Alasdair Mor was succeeded in the representation of his clan by Domhnall. Today he is considered to be the eponymous ancestor of Clan MacAlister.
