|Cornelius O'Brien of Birchfield (1782 - 1857) by Henry Comber|
One tourist brochure names Sir Lucius O’Brien as the
father of Cornelius, another attributes his paternity to Sir Turlough.
However, in spite of this convenient but confusing pedigree, he did not
belong to the Inchiquin family.
“Cornelius O’Brien was the third son of Henry O’Brien, late of the town of Ennis in the County of Clare, Esq., deceased and Helen O’Brien, otherwise O’Callaghan. He is aged at least 16 years. He was educated in the school of Stephen O’Halloran in the town of Ennis in the county of Clare and was reading Virgil when he left same.”
A separate petition dated 12 November, 1802 states that “he studied Grammar, Corderius, Ovid and part of Virgil.”
An entry in the Who’s Who of British M.P.s reads:-
“4 North St., Westminster, London; 20 Summerhill,
Dublin; Birchfield, Ennistymon.
It appears that Henry O’Brien was the son of Kate
McDonough, daughter of Nicholas of Birchfield by her marriage with an
O’Brien of Toonagh.
Son of Henry O’Brien, gen., born in Co. Clare; educated by Rev. M. Fitzgerald; entered Trinity College as Sizar June 5, 1798 aged 19. Scholar 1805, B.A. 1806. He was curate of Hollywood (Glendalough diocese) c.1825.
A daughter, Mary, married John Lysaght of Ballyvorda. They had two sons, Andrew and Henry. Their daughter, Mary, married Michael Finucane of Ballymacooda House, Ennis.
