Hi Kathleen,
Thanks so much for sharing your journey into your family history here! I am so happy you were able to find out so much.
Sometimes records, like the birth certificate from your County Mayo ancestor, unfortunately, aren't there anymore. The reason for this can be the
fire of 1922, or they were simply lost or misplaced over the years. In this case, I think you might be interested in a project called
Beyond 2022.
Beyond 2022 is a project by Trinity College Dublin in collaboration with the National Archives, the National Archives (UK), the Public Record Office of Northern Ireland and the Irish Manuscripts Commission. The project aims to create a virtual reconstruction of the Record Treasury of the Public Record Office of Ireland which was destroyed during the Civil War in June 1922. I am also very happy to see you've been able to visit your family here on the island several times, and I hope we get to welcome you back again in the future.
Thanks again for sharing your experiences with us, and if you ever have any questions, the Community is always here to help! :)
