Landed Estates

Gore (Castle Gore)

In 1666 the Gores were granted extensive estates, over 14,700 acres, in the barony of Tirawley, county Mayo and in county Sligo under the Acts of Settlement. In 1686 the Manor of Castle-Gore was created from these estates and other lands bought by the Gores. They also acquired the Manor of Belleek from the O'Haras, Barons Tyrawley, and owned estates in county Donegal. Their county Mayo estates were centred on the parishes of Ardagh, Ballysakeery, Addergoole and Crossmolina. In the 19th century much of their estate was let to middlemen or administered by agents and the Gores were largely absentee, as they had inherited the Saunders' estate in county Wexford. John Perkins of Ballybroony near Ballina, was their main agent in the 1830s. In 1876 the Earl of Arran owned 29,644 acres in county Mayo and 6883 in county Donegal.
