To all Hourihane and O’Brien families I had a email from a lady today who told me that an Irish 'genealogist' told her that all 'Hourihan/e's from West Cork would originally have been 'O'Brien's'. As Hourihan was a 'sept' name -used for a particular branch of O’Brien’s. If this is true and can anyone give me any more details.

I live in Liverpool and believe there is a lot of truth in what you say as I was also told by someone that my name derives from Hourihane but obviously someone has dropped the e! I was also told that my family name originates from O'Brien and believe that my family are also from County Cork in Southern Ireland.

I have not researched this further as i have never had the time but would be grateful if you have made progress with this? Maybe you could share your findings?

Hi Jacqueline,

I don't know if you saw my reply to Michael. There is an ongoing genetic study to determine what the origins of the Hourihanes were. I have heard of the Hourihane-O'Brien connection too, but haven't had enough testers to prove or refute this claim.

We are actively recruiting. If you have a male Hourihane relative who can fill in, he knows the geographic origin of your paternal ancestor, to the townland or village, and you/he are willing to share your family tree with the project, please email me: as the project would be interested in funding a 37 marker kit for you.

I have heard stories about County Clare / Dal Cais origin also. Dal Cais is connected with the O'Brien surname. So far, our testing results for Hourihanes in west Cork do not confirm these claims. We are also seeking to recruit Hanrahans in Clare, which can help us test these hypotheses.
