Conor O’Brien, 18th Baron Inchiquin Biography, Age, Height, Wife, Net Worth and Family

The family seat of Dromoland Castle was sold after financial strains required Donough O’Brien, 16th Baron Inchiquin to sell a large part of the estate (c. 350 acres) to billionaire industrialist Bernard McDonough. The castle today functions as a luxury hotel and is owned by a number of Irish-American businessmen.

In 1998, Conor O’Brien visited Antioch, California for St. Patrick’s Day and Antioch’s first St. Patrick’s Day Crinniu, hosted by then-Councilman Allen Payton and the city’s council proclaimed “Sir Conor O’Brien Day”.

He married Helen O’Farrell in 1988, and together they have two children.

Although the ancestral seat of Dromoland Castle has since left family hands O’Brien has continued to run the lands on the estate left in family hands. O’Brien ran an exclusive guest house in the new family home, Thomond House, adjacent to the former seat, from 1984 until 2008. O’Brien also turned the residual Dromoland Estate into a sporting and leisure venue. In April 2010, he was awarded €7.9m in damages by the High Court over the repudiation of an agreement to buy 377 acres out of the 600 acres of the Dromoland estate which his family still owned. In 2012, in a long-running dispute with the management of Dromoland Castle, O’Brien was refused an initial application to the High Court for them to immediately return 37 paintings that were loaned several decades prior; the hotel wanted to copy the paintings and then return them, possibly on a phased basis.

O’Brien succeeded to the peerage on the death of his uncle, Phaedrig O’Brien, 17th Baron Inchiquin, in 1982.

The 16th Baron built a smaller residence adjacent to the estate, Thomond House, which he moved into in 1965. Conor O’Brien continues to reside in Thomond House.

O’Brien commissioned into the 14th/20th Kings Hussars of the British Army in 1963. He served as a troop commander in Benghazi, Tripoli, Cyprus on Operation Tosca, Tidworth, Paderborn (as assistant adjutant), Singapore, and Tidworth as adjutant of the regiment. He became Aide-de-Camp to Commander British Forces Gulf in Bahrain and left the army in 1975, retiring with the rank of Captain.
