The Viscountcy of Ferrard was created in 1797 for Margaretta Foster. Her husband John was created Baron Oriel. Thus, their son Thomas inherited both titles.
The third Viscount had inherited yet another title - the Viscountcy of Massereene - prior to inheriting the Ferrard title. Therafter, the two Viscountcies have remained united.
JOHN FOSTER ORIEL, Baron (1740-1828), Irish politician, was the son of Anthony Foster of Louth, an Irish judge.
He was returned to the Irish parliament in 1761, and made his mark in financial and commercial questions, being appointed chancellor of the Irish exchequer in 1784.
In 1821 he was created a peer of the United Kingdom as BaronOriel of Ferrard in the county of Louth, and died on the 23rd of August 1828.
