The way to do this is to gather as many documents as you can from your local registry office and archives, starting with your own birth certificate and then adding those of your parents, four grandparents, eight great-grandparents etc. until you come across your first ancestors who were not born in the same country as you, but rather, in Ireland. Once you know when and where in Ireland your first emigrating ancestors were born, get in touch and we will be able to point you toward the most appropriate records office in Ireland for more detailed information about your relatives.
