The O'Reilly, later Nugent baronetcy, of Ballinlough in the County of Westmeath, was created in the Baronetage of Ireland on 23 July 1795 for Hugh O'Reilly. In 1812, on the death of his maternal uncle John Nugent, he assumed by Royal licence the surname of Nugent.[2] The third Baronet was Chamberlain to the Emperor of Austria and was also created a Count of the Austrian Empire. The family seat is Ballinlough Castle, Clonmellon, County Westmeath.
