Brendan O'Malley

From Brendan O'Malley to JC Lalumière. There were a number of O'Malleys who went to France at different times in history, so their descendants could possibly have changed the name to a more French spelling. One was Colonel Austin O'Malley, who left Ireland after the rebellion in 1798. He had served under the French General Humbert at the battles of Killala and Ballinamuck in Ireland and he went on to fight in Napoleon's Irish brigade. He married a French woman and had two sons, one of whom, Augustin-Andre O'Malley, became a General in the French army and ended his career as commander of the military garrison in Marseille. I have not been able to discover if he had any children. There was also Charles O'Malley who served under Charles ii of england and died in exile at St-Germain-en-Laye and his 5 brothers who entered foreign service in Europe. One fought the Turks in the forces of the Emperor and became a general. I'm sure here were others. I have heard that the Maille family (who make mustard, among other things) have refuted any connection with Ireland, but I know nothing of the Aumailleys. If you have any information on them, please contact me at


My grandmother was born in Donegal in 1916, her maiden name is O'Malley but her brothers surname was McClough. At some point the family lived in Roshine. Would be thrilled if anyone had any information or potential lines of enquiry. Thank you

Amy MacKenzie

I'm looking for any information on my Great-Grandmother, Katherine O'Malley, born 2 Feb 1878 in County Mayo. No town known. Her father was a J. O'Malley and her mom, an Ama/Emma/Anna Derry?? Thank you in advance for any information

Ed V mcmanus

hi how are ya'll

P Macanriogh

My grand aunt, Mary O Malley, emigrated to the USA in the late 1880s. She was born in Ballyconneely,Clifden,Co Galway She eventually settled in Minneapolis, Minnesota and married a man of Polish heritage. I understand that she had children. She was in contact with my mother until the late 1050s. I've tried to trace her/her descendants but without success. Can anyone supply any information?

Mary Kay O'Malley

In the 1800's 7 brothers emigrated to the USA and homesteaded the area around Perry, Iowa. Our family is descended from the brother named Martin. My great grandfather, James F. O'Malley died after his car was struck by a train around 1919 and my grandfather, also James F., farmed until the depression when he moved his family including my father, you guessed it James F., to Kansas City, Missouri. My father was a doctor in Kansas City and passed away in 2012. Ii am one of 7 kids and my parents already have 31 great grandchildren with more likely to follow. God bless all the O'Malleys, a proud and prosperous clan! BTW my mother's clan of mccormicks, Fitzgibbons and Quinlans came from Mayo and Donegal.

Leslie O’Malley

Leslie O’Malley My O’Malleys came from Steelaun/Rathfran in County Mayo. The earliest ancestor I can find was Patrick O’Malley. He was married several times but I am descended from Maria McHale. Their son Martin married Maria Weir and was also a carpenter in Steelaun. Their son “Big Mick” (5’10”) came to NYC, married Annie Kearney and they had a son Michael born Christmas Day, 1910. Shortly after the Titanic went down, the family return to Steelaun and then settled in Dun Laoghaire, Co. Dublin. I am the daughter of Michael Stephan Christopher O’Malley and Florence Scanlon, born in Carrownagh, County Sligo.


I am having tremendous problems finding where my father came from. I do know he ( John James O’Malley) was born in Donegal in 1915 but all my research has failed to show anybody of that name born in 1915 in Donegal. There is someone born in 1913 of a similar name but the date of birth on my father’s death certificate and marriage certificate have to align with a birth certificate date of birth so I can get an Irish Passport. Even my DNA says Donegal!

James Morgan

My grandmother was Delia O'Malley from Peter Street, Westport (Mayo). She married Jim Lyons from High Street, Westport and they had five children. My mother is the third eldest. Is there anyone on here who might be related? I'm having trouble finding Delia's birth or baptismal records, though I have found details of her marriage and also some old censuses. She and I were said to share the same birthday (10th June), but the year of her birth has been given as 1892, 3 and 4. I can't find anything under any of those years.

JC Lalumière

I am wondering if the french name Aumailley could be an aletration of O'Malley. Do you have any clue about that ?

Steven David Malley

Hi my name is Steven Malley I live in Cheshire England and my parents (father Thomas Malley) was from Liverpool. I would like to trace my ancestry I presume to the Cork area in Ireland. Can you help? Many thanks


To Jezreel Lopez, It would be great if you joined the O'Malley project on FTDNA ( You can upload your family tree and look for DNA matches to all the O'Malleys who are part of the project. We are trying to identify a DNA signature for descendants of Grace O'Malley, so your family tree and DNA analysis would be a great help. Regards Brendan O'Malley (Co-Administrator)

Jezreel Lopez

I just discovered my connection to my long lost Irish roots! Grace O’Malley, the infamous pirate queen, was my 15th great grandmother through her second husband Bourke. I’ve been to Ireland and have always loved it, and the golden age of piracy was always a fascination for me! I hope one day I can return to see all of the O’Malley sites now that I know my heritage ??

To: irishomalleygirl. Who was your great grandfather and where did he come from? If you know the dates and places of his birth, marriage and/or death, then you should be able to find some traces of him and some leads further back.
