THE VISCOUNTS DILLON WERE MAJOR LANDOWNERS IN COUNTY MAYO, WITH 83,749 ACRES


SIR HENRY DE LEON (son of Thomas, Duke of Aquitaine), who was brought into England with his brother Thomas, when an infant, by HENRY II, the deposer of his father; and accompanying the Earl of Morton (afterwards KING JOHN) into Ireland, in 1185, obtained those extensive territorial grants in the counties of Longford and Westmeath then denominated Dillon's Country, but altered by statute, in the reign of HENRY VIII, to the Barony of Kilkenny West.

Sir Henry married a daughter of John de Courcy, Earl of Ulster, and was afterwards styled "Premier Dillon, Lord Drumraney".

LOUGHGLYNN HOUSE, County Roscommon, is a five-bay, two-storey mansion house, built ca 1715.

Although Loughglynn is in County Roscommon, the vast majority of the Dillon estate straddled the border with County Mayo.

A third attic storey was built in the 1820s, though suffered a disastrous fire in 1904, when the top storey was not replaced, nor the end bays on the garden front which were reduced to a single storey.

There are ashlar limestone walls with quoins and a with roughly tooled limestone basement.

The entrance front has a pediment and a pedimented Doric door-case.

In 1903, Loughglynn was sold to the Catholic Bishop of Elphin, who invited the Franciscan Missionaries of Mary to establish a convent.

The sisters established a dairy, and Loughglynn butter and cheese was famous all over the world until they ceased this activity in the 1960s.

They subsequently opened a nursing home.
In 2003, the property developer Gerry Gannon bought the convent for under €2m, intending to turn it into a hotel.
In 2009, it was transferred to his wife's name.
THE DILLON FAMILY lived mainly at their Oxfordshire seat, Ditchley Park.
