Gillick

The surname (Mc)Gillick is a patronymic adopted by a branch of the Burkes of Connacht, and originates from the Irish Mag Uilic, meaning 'son of Ulick'. Mag is a form of Mac (son) used in old Irish names before vowels. William is Uilliam in Gaelic, and 'William the Younger' is Uilliam Og. As time passed, Uilliam Og was contracted to Uilleog, anglicized Ulick, which literally means 'young William', but has also come to mean 'little William'. The name Ulick came into use amongst the Burkes in the 14th century, and was originally peculiar to this family.

The Gillicks have as their eponymous ancestor, Ulick de Burgo of Umhall (confused by MacFirbis with Ulick de Burgo of Annaghkeen, a contemporary kinsman), and descend through his son, Henry MacUlick. The deaths of both are recorded in the Annals of Loch Cé:

1343: Ulick son of Richard son of William Liath, the greatest of all the foreign (i.e. Anglo-Norman, not native Irish) youths in Ireland in bounty and prowess, quievit.

1359: Henry son of Ulick son of Richard mortuus est.

The descendants of this Henry used MacUlick as a surname, but the clan name was MacHenry.

The 'Division of Connacht and Thomond' places the land of Clan Henry in the barony of Dunkellin, and names among the gentlemen and their castles:

The Composition of Clanricard in 1585, states that 'Pobbil Clanhenry' of the east comprised 28 quarters. The principal seat of the MacHenry Burkes was Gortnamackan. This castle is in that townland in the part of the parish of Kilchrist which is in Dunkellin barony. Cahergal also is in that townland of Killogilleen parish. Creggymulgreny is now shortened to Cregg Castle. These castles form a group in the east of the barony.
