askaboutireland.ie/griffith-valuation

A comprehensive valuation of property in Ireland was overseen by Dublin geologist Richard Griffith between 1847 and 1864, listing landholders and householders. This free website is pretty long in the tooth, and there are other places online where you can find the data, but it still has lots going for it. From the list of results after searching for a surname (you can include a forename too, and specify an area including a Poor Law Union), you can read a transcript of the information, view a scan of the original page, or launch a map view. This opens up an external Google Maps layer, where you can use a transparency slider to switch between 19th- and 21st-century Ireland.
