Irish County Links
The links on this page will give you a starting point to delve into the locality where your ancestor lived. Many are collections of links for a particular County and some sites have separate pages for each County. Since each site is maintained locally, you may find broken links on their page which I can't control. If, however, a link on this page is broken, please email me so I can fix it or delete it. Also, if you've found a valuable website, let me know and I'll add it. I'd encourage you to still "google" the name of your county (or even parish) with the word genealogy. You may find additional resources to assist in your research.
