The descent of the Earls of Dunraven from the ancient Milesian princes is certified by the recognition of the pedigree of their ancestor, Thady Quin, of Adare, in a record entered in Ulster King-of-Arms' office by Sir Richard Carney, Knight, Ulster King-of-Arms in 1688.
Con Cead Caha, or Con of the Hundred Battles, described by genealogists as monarch in Ireland in the 2nd century, is represented as the founder of the family of QUIN; his grandson, Cormac, who is said to have reigned in AD 254, was the first who adopted the surname of QUIN, which signifies a descendant of Con.
The family certainly possessed large territories in Ireland, and governed as hereditary chieftains, before the invasion of the English in the reign of HENRY II.
The Earls of Dunraven descended from a branch which for many centuries possessed great feudal power in County Clare, whence their ancestors were finally expelled by the more powerful family of O'Brien, and settled in County Limerick.

Adare Manor was originally a two-storey, seven-bay early 18th century house, most likely built about 1725 by Valentine Quin, grandfather of the 1st Earl of Dunraven.
When the house was almost completed in 1846, A W Pugin was commissioned to design some features of the Great Hall.
The Long Gallery above is 132 feet long and 26 feet in height.
The house is set on a 840-acre estate and now operates as a luxury hotel, featuring the Adare Golf Club, Elemis Treatment Rooms, Townhouses and Villas on the rest of the resort.
President Clinton stayed at Adare Manor in September, 1998.
