Amy of Garmoran

[1][2] After her marriage had produced three sons, the ambitious John of Islay divorced her in order to remarry and cement his links with the House of Stewart.

[5][Note 1] When her distant cousin Alexander of Argyll's support of the opponents of King Robert the Bruce led to the forfeiture of his lands, they were distributed between Aonghas Óg of Islay and Ruaidhri mac Ailein.

[3][Note 2] Bruce was however careful to ensure his interests in the west were protected and Dunstaffnage Castle was given not to Ruari, now styled the "High Chief of Lorn" but to a royal constable, Arthur Campbell.

By marrying this heiress to the Mac Ruaidhri lands he eventually controlled significant stretches of the western seaboard of Scotland from Morvern to Loch Hourn and the whole of the Hebrides save for Skye.

[4][13] The Lord of the Isles now received Knapdale and Kintyre as a dowry but in return his sons by Amie were to be passed over in the succession in favour of any children by the marriage with Margaret.

[13][16] The "unvarying tradition" of the Gàidhealtachd recorded in the late 19th century was that Amie had given her husband no grounds for divorce and lived alone on her own estates until her death.

[4][19] MacGibbon and Ross also attribute the building of the tower of Borve Castle, located to the south-west of the island of Benbecula, to Amie and dated the work to between 1344 and 1363.
