Mary Lennox

Wrong generation to be a daughter of Malcolm, 5th Earl of Lennox

Alastair Carragh MacDonald (Alexander the Strong) (d. c.1440) was a son of John of Islay, Lord of the Isles and Margaret Stewart, daughter of King Robert II of Scotland and Elizabeth Mure.[1] He is the eponymous ancestor of Clan MacDonald of Keppoch.

By his wife Mary (b. 1365), daughter of Malcolm, Earl of Lennox [SIC], they had the following known issue:

1. Angus, d. c.1484, married a daughter of MacPhee of Glenpean.
2. Alexander MacAlastair, b. 1400, d. 1465

Mary was born before 1375, a daughter of Earl Malcolm of Lennox. The Earldom of Lennox was a, area north of Glasgow around Loch Long, Gare Loch, Loch Goiul and Loch Lomond. It bordered the lands of the Lords of the Isles which were further west. The true extent of these lands are now lost but suggested to have included the whole of the ancient sheriffdom of Dumbarton, the parishes of Arrochar, Baldernock, Balfron, Bonhill, Buchanan, Oardross, Drymen, Dumbarton, Fintry, Killearn, Kilmarnock, New Kilpatrick, Old Kilpatrick, Luss, Roseneath, Row, and Strathblane, with Campsie and Kilsyth.

If Mary was a daughter of Malcolm we can only presume this to be Maol Choluim II, Mormaer of Lennox, who died at the Battle of Halidon Hill 1333. This Malcolm was a strong supporter of Bruce.

Given the dates this does not seem possible, although has been diligently copied on wikipedia, and warrants further investigation. There was a relationship between the two families. Duncan, 8th Earl of Lennox married, sometime before 30 March 1373, Ellen or Helen Campbell, daughter of Archibald or Gillespie Campbell of Lochawe. She was the widow of John of the Isles, apparently the eldest son of John, first Lord of the Isles, by his first marriage with Amie, daughter of Ruari of Bute.[1] John of the Isles died about 1369, leaving Angus, who died a youth. Between 1369 and 1373 his widow married Duncan, then styled son of Walter Macallan of Foslane. Her first marriage is referred to in a dispensation for which they applied on the ground that although they knew that John of the Isles, Helen's first husband, and Duncan were related in the third and fourth degrees of affinity, yet to pacify serious feuds and prevent murder and bloodshed among their kinsmen and friends, they had contracted marriage "per verba de futuro", and had issue, thus incurring the penalty of excommunication from which they petition to be relieved, and their marriage sanctioned.
