Irish researchers may be interested in "a comprehensive and integrated resource guide to landed estates and historic houses in Connacht and Munster, c. 1700-1914" at http://landedestates.nuigalway.ie:8080/LandedEstates/jsp/.
You can search by estate, family (2,700) and house (4,500 including images). There is a map of the locations.
A tip of the hat to Jane MacNamara for pointing me to the website for this project and commenting that the list of "Reference Sources" which has some wonderfully obscure titles. I surfed around and chanced on:
- a project "Death and Funerary Practices, 1829-1901" to digitise, preserve and disseminate a substantial hand-written, local history collection of nineteenth-century newspaper obituaries, hedgestone inscriptions and maps of burial grounds dating from Catholic Emancipation to Queen Victoria’s death (1829-1901).
- a flickr set of photos of Munster, at http://www.flickr.com/photos/nlireland/sets/72157625431868193/
