    Don’t forget the Thomas surname. There are clusters of this surname in the Errew / Ballyheane area of Castlebar.

  2. Patrice Houck Schadt says

    I have Hallinan, Ferguson and Durkin. I also have a casual interest into Kneafsey. Michael Kneafsey married Margaret Hallinan, a sister of my great grandmother, Ellen Hallinan Bagley.

  3. Margaret Geraghty says

    Could you please add GARVEY (my line are from Brownstown/Coolylaughnan, looks like they left the area and disappeared by about 1880). Thanks

    • Barbara says

      Eileen – my husband’s grandfather was Patrick Cassidy b, 1854. Family lores says he was from Mayo but I have found no records. He had 4 sisters Mary, Beatrice, Ellen and Catherine. Their parents were Patrick and Mary Doherty Cassidy. Would they be related to you?

  4. Julie Plant (Nee Bermingham) says

    My maiden name was Bermingham descending from John Richard Bermingham born in Co. Mayo around 1820. Some Trees note his father as Henry and a death certificate has his place of birth beginning with Ball which we now believe likely to be Ballinrobe He was in Australia and married Mary O’Hara, around 1849. Mary was an Irish orphan girl who went to Melbourne on the Lady Kennaway and born in Crossmolina.

  5. Maureen says

    My Grandfather was James Hyland from Castlebar and my grandmother was
    Delia Roach(e) also from Castlebar. They both appear in the 1911 census

  6. Colleen Ivey says

    There are also Caseys in County Mayo, in Derry, Owenbrin, Cappaghduff District.
    Thank you for such tremendous research!

  7. grace sullivan says

    my let name is Sullivan. it was O’Sullivan but my ancestors changed it after they came to america from county mayo. i think Sullivan should definitely be up there.

    • Mike says

      Hi Grace – these are the names of our readers and the counties their ancestors came from. Yours is the first Sullivan from Mayo – so now its up there :)

  8. delores says

    could you add Williams,and Lane? Hickey I found they were from County Meath,Ireland.Way back in time there Williams may have been spelled differently,and Lane could of spelled different too,cause my Williams came on ship from Londonderry,Ireland,and Lane from Ulster,Ireland.Hope it was ok to send you this much out.

    • Mike says

      Hi Mary Ann – lots of Pattersons all around the counties of Ulster. When found in Mayo it is usually another version of the Gaelic Irish name Cussane. Mike.

  9. Glen Francis says

    Please add Friel and Freil to the surname list from Letterbrock County Mayo, which is near Westport at the foot of the “Reak”. This is where my mother is from. Glen

  10. Catherine Caffrey says

    Please add Cafferty- from Rathmore, Crossmolina, North Mayo. My ancestor Martin was christened there in 1833. His mother’s name was Catherine Murphy – I see you already have Murphy. Thank you!

  11. Casey says

    We came from Mayo County in 1845 – a widow and 3 or 4 sons. Our name is McGrayel but at least three other spellings have been printed in US newspapers ( McGrail, Mc Greal, McGrayle, McGroyal).

    • Mike says

      Hi Casey – I have now added your McGrayel to our list for Mayo. The different spellings can be confusing but at least all of these spellings sound the same (almost). Mike.

  12. Tracy says

    There is a Tucker’s Lough outside of Castlebar, and a Tucker Street, in Castlebar itself. In fact, I believe the Taoiseach has his constituent office on Tucker Street.

    Please add the Tuckers to the list of distinguished names of Co. Mayo.

    Thank you…!!!

  13. Kathy P says

    Hi Mike,
    You can add Pue to that list! Thanks and wonderful update!! Love it! Great work to you and Carina!
    Enjoy your weekend and tea.

  14. Paul says

    Please add O’Rourke to the surnames of Co.Mayo. My gr.Grandfather came from Annagh nr. Ballyhaunis. though I believe the name originates from Leitrim/Sligo.

    • Mike says

      Hi Paul – your O’Rourke now added to Mayo. O’Rourkes were originally lords of Leitrim (or as it was called Breffni). Mike.

  15. Debby says

    Please add KENNEDY to the list. My ancestors came from Upper & Lower Barnhill area in Lacken. I’ve hit a wall taking they back before Patrick Kennedy (born 1785) and his descendants who remained in Ireland.

  16. Suzy says

    I may have missed it, but I do not recall seeing the names Flatley or Grogran
    My great grandfather, William Flatley was born in Claremorris in ~1864,
    and my great grandmother, Delia Grogan was born in 1873 in Ballyhaunis.
    Thank you!:)
