The settlement was originally known as
Kilcubin, which is thought to come from
Irish Cill Ghobáin, meaning "
St Goban's church". This later became Kirkcubbin, from the
Ulster-Scots word for church,
kirk.
1798 Rebellion Archibald Warwick, a
Presbyterian licentiate and member of the
United Irishmen from Kircubbin, was hanged in 1798 near his church, for participating in
Irish Rebellion of 1798.
The Troubles Two significant incidents occurred during
the Troubles. In 1974, St Mary Star of the Sea Church, Nunsquarter, which still stands and is used today, was badly damaged by a bomb planted at the side door of the chapel. One man, a local joiner who was working in the church hall adjacent to the church, left the premises shortly before the bomb went off.
