Hi Shane and thanks for the very quick reply!
Yes that family you found on the 1911 census does seem to be my family, the daughter "Mary Anne" is actually my grandmother. Unfortunately I haven't been able to locate a birth record for Mary Anne, but I managed to find one for her brother John. That's where I got the mother's name of Ellen Kenneally. I then found a marriage for an Ellen Kenneally and Jeremiah Walsh in Thurles in 1902. But there seem to be so many Ellen Kenneallys (or derivatives of that name) and I now am struggling to find her parents. On the marriage cert it states that her father is James Kenneally, but I can't seem to find one on the Ancestry website that matches up with the info I have.
As for the Walsh side, Jeremiah Walsh's father is listed on the marriage cert as John Walsh, and there are loads of them!!!
