Last night I ran across a blog post with new (to me) information on Griffith's Valuation. I would guess that most of us interested in Irish Genealogy know about this resource. But for those who don't, it is perhaps the most important set of records for most of us interested in tracing our Irish families to the mid 1800s. Check out this blog entry: http://irishfamilyresearch.blogspot.com/2010/01/griffiths-valuation.html . The link to search engine for an online version of Griffith's is well-worth the click.
I've added this blog http://irishfamilyresearch.blogspot.com/ to those I'll be following on a regular basis.
