The following are websites that I think might help with researching in Ireland:
http://griffiths.askaboutireland.ie - information contained in Griffith's Evaluation - names, townlands, occupiers, owners, etc.
http://waterfordcountylibrary.ie/en - Right-hand lower corner are links for the OSI Historical Mapping Archive (can be printed;
large sizes can be bought) and Griffith's Primary Evaluation of Ireland and a link for the
Irish Times Digital Archive (paid subscriptions, but can be for only one day).
Left-hand upper corner, there is a listing for Family History, and from there you can get into
a Death Register for Waterford County. There is also a lot more information for Waterford
County on this site.
