Discovering exactly where your Irish ancestors hailed from can be a tricky exercise, especially with the lack of 19th century census returns. However, there is an abundance of other records that can help in your research, and this talk focuses on Griffith’s Valuation and the subsequent Revision (or Cancelled) books – what they are, what they can tell us, and where you can access them. Case studies are used to highlight a range of sources that can help you identify your family in these records, and discover the place where your ancestors left their footprints in Ireland.
