The MacDougalls, formerly exiled from their Argyll lands in the reign of Robert I, King of Scotland (died 1329), had been restored to their Lorne lands in the reign of David II, King of Scotland.
The close association between John Gallda and David meant that the former was out of favour in the succeeding Stewart regime under Robert II, King of Scotland (died 1390).
When John Gallda died without a male heir his two legitimate daughters, including Isabel, were subsequently married off to the sons of John Stewart of Innermeath.
Robert Stewart, 1st Lord of Lorne was succeeded by his oldest son John, member of the Parliament of Scotland.
Walter Stewart resigned the lordship on 30 November 1463, or 17 April 1470, and was created 1st Lord Innermeath on the same day.
