Randall MacSorley MacDonnell, 1st Earl of Antrim, PC (Ire) (died 10 December 1636), rebelled together with Tyrone and Tyrconnell in the Nine Years' War but having succeeded his brother, Sir James mac Sorley MacDonnell, as Lord of the Route and the Glynns in 1601, he submitted to Mountjoy, the Lord Deputy of Ireland, in 1602.
[1] In his youth, Randal was fostered in the Gaelic manner and lived with a Presbyterian Stewart family on the Scottish island of Arran.
[2] His father died in February 1590 at Dunaneeny Castle near Ballycastle and Randal's elder brother James succeeded as Lord of the Route.
[3] In 1597, MacDonnell gave offence to the English Crown by helping his brother James to fortify Dunluce Castle.
His brother James died suddenly on 13 April 1601 at Dunluce Castle, leaving the eldest son Alistair Carragh (or Alexander), but MacDonnell was designated as successor by tanistry.
[5] In August 1602 he submitted to the lord deputy at Tullyhogue, offering to serve against Tyrone in Fermanagh with five hundred foot and forty horse at his own expense.
[7] In 1604 MacDonnell married Aellis, Elice, or Alice, who would die in 1665,[6] third daughter of Hugh O'Neill by his second wife Siobhán O'Donnell.
His fourth part of the fishing of the River Bann, which he regarded as "the best stay of his living," involved him in a long and profitless controversy with James Hamilton, 1st Viscount Claneboye.
He appeared voluntarily before the Lord Deputy of Ireland, Sir Arthur Chichester, denied the truth of the charge, and experienced no further trouble on that account.
[19] Shortly afterwards he was admitted a member of the Privy Council of Ireland, appointed Lord Lieutenant of Antrim,[20] and placed in command of a regiment.
He at once confessed his fault, promised never to fall into the like error again, and was graciously pardoned, but compelled to pay the reward due to Boyd for his information against him.
