Biography
After the death of his father Alexander MacDonnell in 1539, his older brother James MacDonnell, inherited the title of Lord of Dunnyveg and Antrim Glynns, however James decided to return to Scotland, accompanied by his wife Agnus Campbell. Colla was appointed Captain of the Route to rule the Glynns in his absence.
Colla's marriage to Evelyn MacQuillan, brought a tentative peace between the previous opposing clans.
Attempts were made by Thomas Radclyffe, 3rd Earl of Sussex, Lord Lieutenant of Ireland, to expel the MacDonnells back to Scotland. Colla built a two storey castle, known as Kinbane Castle in 1547, with a large courtyard with traces of other buildings, probably constructed out of wood.
