From An O’Hearn Family History (page 123):

O’AHERNE, Hearne, (O’Heffron).

This Irish surname was first anglicized O’Hagherin, which is a fair phonetic approximation of the original Gaelic O hEachtighearna, derived from the Irish words each a horse and tighearna a lord. Later this was corrupted to O’Aherne and finally the prefix O was dropped. The O’Ahernes were originally a Dalcassian sept and up to the middle of the fourteenth century they were dynasts of Ui Cearnaigh, their territory being in the neighborhood of Sixmilebridge, County Clare, not far from the city of Limerick. In the course of time they migrated southwards and in 1659, when Petty’s census was taken, the name was numerous throughout Counties Cork and Waterford. At the present time, it is almost confined in County Waterford. In this connexion it should be observed that Hearn is a fairly common indigenous name in England, so that persons so called in Ireland may be immigrants from that country.

The Bishop of Kerry from 1336 to 1347 is described in the records as Alan O’Hathern alias O’Hachierane. The most noteworthy of the name in modern history were John Aherne (c. 1769-1806), United Irishman and intimate friend of Wolfe Tone, who, after the latter’s death, became and officer in Napoleon’s Irish Legion; and John Aheron, author of the first book on architecture printed in Ireland (1754).

The Gaelic name O hUidhrin, that of an Offaly sept, has also been anglicized Hearne, Heron etc., though Heffron and Haveran are more usual forms in English. Giollananaomh O hUidhrin (d. 1420), who completed O’Dugan’s celebrated “Topographical Poem,” is usually called O’Heerin in English.

  2. .. 5 Suzanne Elizabeth O’Hearn (1924 – ) b: 1924 passed away a few months back but published a family tree in book form on the Daniel O’Hearn side several years ago. I’m hoping you were able to get some of this from her. The O’Hearns will gather at Arlington National for her and her husband’s (Robert G. Mills) internment in June. She would have loved to have seen this site. Great Job!

    1. @John Cross

      I’m sorry to hear of Suzanne’s passing. I know she and my grandmother, Elizabeth Ann Melby, had been in contact and I got a copy of Suzanne’s book before my grandmother passed.

      I haven’t done such a great job keeping up with the website. So now I’m going through and trying to respond to everyone who has left messages and such. I guess you can say this is a New Year’s resolution of mine. I hope all is well and to hear from you again.


  3. You list:
    4 John Reese O’Hearn b: 1908 d: 1971
    + Rosemary Murphy b: 1912 d: 1971
    5 Margaret O’Hearn b: 1940 d: 2007
    + Private

    John and Rosemary also had two additional children, a son and a daughter, who are still living.

    Margaret’s husband was Harold Walter (1935-2013); they were divorced but had two sons and a daughter.

    Would be happy to share information if you’d like to contact me; I am married to one of the sons of Margaret and Harold.

    1. Hi Paul Olin. You are 4th cousins with my husband – his mother was Margaret Therese (O’Hearn) Walter, daughter of John Reese O’Hearn & Rosemary Murphy. Going backwards from John Reese O’Hearn:
      John Matthew O’Hearn / Elizabeth M Reese
      James Joseph O’Hearn / Jane McGrath
      John Berton O’Hearn / Mary McCarty
      Daniel O’Hearn / Ellen Curley

      If you’d like to get in contact, respond here and I will post my email address.

      Jamie Davie-Walter
