Origin & Meaning of Irish Surnames

Irish surnames reflect the history of Ireland and in particular the various waves of immigrants and invaders who came to the country over the centuries, intermarried with the Irish population or simply never went home. Over the centuries the Irish emigrated in such large numbers to every corner of the globe, that it is now a rare place that you will not find surnames which originated here.

The Origins of Ireland’s Surnames

It is easy to think that Irish surnames are all Gaelic in origin, but it’s far from the case. While the majority have Gealic roots, the various waves of settlers and conquerers that came to Ireland over the centuries brought their names with them and many surnames which are nowadays looked on as ‘typically Irish’ are not in fact Gaelic in origin. Alongside the most numerous Gaelic surnames, which are invariably the oldest found in Ireland, there are almost as many names of Norman or English origin and quite a few with less common but often fascinating histories, such as those of Viking and Huguenot origin. For information about each of these categories of names, please use the links below: Gaelic Names | Norman Names | English Names | Viking Names | Huguenot & Palatine Names

    I am looking for  the surname Bohan or Bowen from Muir or Latherham. The family came to England in the  late 1840’s. Can’t find the places either, assume they were small villages which disappeared in the famine?
    thanks
    margaret

    • Katherine says:

      Muir and Latherham are not Irish places and I am certain they never were. They sound like places in England to me, or possibly Scotland. While many small villages disappeared during and after the famine, the place names tended not too, so would still be around if they had existed.

    • Nicola says:

      The name Bowen in Ireland is often of Welsh origin being another form of the anglicized name Owens, often used instead of MacKeown. It was also used as a form of the Norman name de Bohun from the twelfth century onwards. Bohane is another variant.

      Cant locate any existence of the place names you mentioned.

    Good evening,
     
    I am looking for the origin and area of my family name Larkin.  I have been told Galway but not sure. My family  left Ireland and went to Philadelphia but not sure when.  That side didn’t talk about it and by the time I was old enough to inquire they were all dead.
     
    Thanks

  • Colleen says:
