Sir Conor O’Brien

August 5th, 2011 by Paul O'Brien

Conor O'BrienThe O’Brien, Prince of Thomond, Chief of the Name, The 18th Baron Inchiquin, 10th Baronet of Leamaneh – aka “The Great Condor” for flying, rather than driving, his Aston Martin.

Conor Myles John O’Brien born in Surrey, England on 17th July 1943, the son of the youngest son of 15th Baron Inchiquin, The Hon. Fionn Myles Maryons O’Brien who married Josephine Bembaron in 1939. He has one sister, Fiona, who is married to Romano Obert de Thieusies.

He became Chief and Peer on the death of his uncle Phaedrig, the 17th Baron on 20th May 1982.

He lives on Dromoland Estate in Thomond House, which is next to Dromoland Castle. Dromoland Castle was the home of the O’Briens until 1962, when Bernard McDonough turned it into a luxury 5 star hotel, in 1963.

Conor was educated in England at Eton College, served in the British Army, 14th / 20th King’s Hussars in the Middle East, Far East and Europe from 1962 to 1975. He has lived and worked most of his life abroad, with 10 years spent in the Far East, Hong Kong and Singapore, running his own trading company for seven years, finally in Financial Services in Hong Kong before returning to live in Ireland in 1982.

In 1988 he married Helen Farrell of Newtown Forbes, County Longford. They have two daughters, The Hon. Slaney O’Brien, born 1989 and The Hon. Lucia O’Brien born 1991. The family run an exclusive guest house in their home Thomond House at Dromoland, as well as having turned Dromoland Estate into a major sporting and leisure centre. Activities include, driven pheasant shooting, stalking, fishing, horse riding, eventing, hunter trials, clay pigeon shooting, archery and other activities.

He is presently the Chairman Dromoland Development Company Limited and of an UK Development Company, Swift International Developments Limited.

July, 2004; Sir Conor receives an autographed copy of President Clinton's book in exchange for his presentation of the Historical Memoirs of the O'Briens on behalf of all members of the O'Brien Clan.

Conor O’Brien, as Chairman of “The Standing Council of Irish Chiefs and Chieftains”, is another Chief who believes there is a place for him in modern Irish life. He says, “with the tremendous interest in roots and Clans, the Irish Chiefs have a major role that they can play in the Gaelic and cultural heritage of Ireland and in helping the state authorities in the promotion of tourism through the medium of the Clan Associations and Clan Gatherings as well as ensuring that the country recognise the importance of the link between the old Gaelic culture and our modern day Republican culture.

Conor is also an advisor to the making of the film “The Lion of Ireland” based on the best seller historical novel by Morgan Llywelyn. It is hoped that this film will be made in the next two years and the script by William O’Brien is presently being considered by a number of well known film directors. Conor was responsible for the formation of the O’Brien Clan Association and the First Clan Gathering for 400 years in 1992. He has formed “The O’Brien Clan Foundation” worldwide and this was launched in the USA on 17th March 1998. The latest Clan gathering was in Ireland at the Brian Boru Millennium Festival, 2002 in Killaloe, Co. Clare, to commemorate the 1000th Anniversary of the accession of Brian Boru to the throne of Ireland.

His interests are in securing Dromoland Estate for the next generation, history, trees and wildlife as well as travel, skiing, shooting and motor cars. He is a member of the Kildare and University Club in Dublin.

    To Sir Conor O’Brien and family,

    What a pleasant surprise to find your informative website! It is very well done!!

    I am a 30th great-grandson of Brian Boru – King of Ireland through several different lineages.

    My Father & I will be staying at Dromoland Castle Hotel & Country Estate beginning on May 4, 2012. We have scheduled ourselves for many Estate Activities and we look forward to immersing ourselves into the history of your fine facility.

    Congratulations and keep up the great work of preservation of the O’Brien Clan and Dromoland Castle.

    Your friend in music (and distant cousin),

    Morgan (Murrough) O’Brien married Eleanor Butler daughter of Edward Butler of Bansha having issue William O’Brien Butler who married Catherine Butler of Baron Dunboyne. This is my DNA connection to you Conor.


  • Douglas Chase Says:

    Thanks for this great information about the O’brien family tree. My grandfathers name was Wilfred O’brien and I just wanted to see a little history into the name.

    I got your invitation to the 1000 year clan reunion. It was not feasible to do, but the events of 9/11/2001 made flying an undesirable mode of transportation due to the installation of ill trained minimally paid TSA goons at all the airports, openly stealing what they want.

    I am the Owner/President/CEO of the Florida Film Investment Company (FFI). If you go to to watch my movie DVD, Oliver Twisted (2000) with Erik Estrada and Karen Black, use Google Chrome or Mozilla Firefox, or you may not see all of my channel, like the banner at the top or my other important posted links. There never was a UK release. The movie was pirated by con artist thief Eric Louzil to the UK from a VHS tape that was made for the stockholders to review before nine minutes was removed to make the movie the standard length for television. Corrupt mega conglomerate corporations and companies flagrantly market Eric Louzil fakes to Europe and India, including amazon and ebay.

    I am also a member of the Skywatcher Tribe.
    The Atlantians were tall, white, with red hair, and spread out after Atlantis sank over 10,000 years ago, so many Irish clans may be of Atlantian descent.

    I would like to eventually do and film paranormal investigations in Ireland, ghosts, UFOs, cryptids, et cetera, like the Ghost Hunters (TAPS) team did and there are some new groups located in Ireland I would like to work with. I saw a ‘Ghosts of Ireland report that included the O’Brien Castle/Tower near a cliff.

    I would also be interested in a role in your ‘The Lion of Ireland’ movie, if there is any way that can happen. I appear in ‘Oliver Twisted’ (2000), and a few times in HBOs ‘From the Earth to the Moon’. I was filmed for ‘Instinct’ with Anthony Hopkins, ‘House on Haunted Hill’, a New Coke commercial featuring Seal for the Asian market, George Romero’s never completed ‘Jacaranda Joe’, and Disney’s ‘Emerald Cove’ but I have not been able to review the first two frame by frame and may never see anything of the others. Some of what I did with ‘The Omega Society’ years ago and do with the Skywatcher Tribe can be viewed by following the links from my channel, “Our Sci-Fi Videos” but we have much more to upload.

    I noticed the shield has the three lions all the same size and one color instead of two. I have seen many variations on the O’Brien coat of arms and wondered what is official. The ones with the lions in two colors looks odd. There is a carving in the Cinderella Castle in Disney World that looks like the O’Brien shield, any connection?

    Are you aware there is a free online adventure game called ‘Prince of Thomond’ on many sites? Did you have anything to do with that?
