[2] In the following year Dubhghall mac Suibhne granted to the earl the lands of Skipnish, Killislate, and others, being that part of Kintyre called South Knapdale and the parish of Kilcalmonell.
[3] About 1263 the earl was Sheriff of Ayr, and aided in making preparations to repel the expected invasion of King Haakon IV of Norway.
He, Countess Mary, and a party of Scots barons traveled to Norway accompanying the princess and her dowry of fourteen thousand marks.
In 1289 he was present at Birgham, and approved of the marriage proposed between Prince Edward of England and the young Margaret, Maid of Norway as she was called, the heiress of the Scottish Crown.
This is the last certain record of him, as although letters were addressed by the English King to Walter Stewart, Earl of Menteith, on 29 June 1294, it is not clear that he was then alive.
He may even have been dead by 10 February 1293, when Balliol's Parliament directed the lands of Knapdale belonging to the earl to be incorporated in the sheriffdom of Lorn under Alexander of Argyll.
