The IrelandGenWeb Project http://www.irelandgenweb.com/ has a wonderful set of genealogical data that is constantly being updated by a group of dedicated volunteers. From the IrelandGenWeb site:
“Welcome to the IrelandGenWeb Project homepage. This site is part of the WorldGenWeb Project and is the local resource index page for Ireland research. To learn more about the history of this project or to contact us for more information, please visit our About This Project.
If you would like to know when any of the County webpages have been updated with new records or of any new projects going on at the IrelandGenWeb Project, join the IGW-L mailing list. This is just an announcement mailing list and will not create a lot of mail.
However, we have a wonderful genealogy list which covers the genealogy, history and the culture of Ireland. It covers all the counties and is a great place for you to learn new research methods and make connections. You can join the list at the Ireland GenWeb Project mailing list webpage.”
