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.

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)

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 ??
