Brent Banta sent an e-mail to notify me of a great site of interest to anyone researching Irish. I looked at the site and I agree with Brent. I was going to write about it until I realized that Brent had already written everything that I was going to describe.
Here is Brent's message:
This site is a certified jaw-dropper: http://griffiths.askaboutireland.ie/gv4/gv_family_search_form.php
Not only does it provide surname and place name searches of Griffith's [Valuation], it has townland maps with the tenement numbers and lot boundaries overlaid. (This info is very difficult to locate on Family History Library microfilms.)
For good measure, the townland maps are linked to satellite images and modern highway map overlays!
Well said! All I can add is that anyone researching Irish ancestors should look at this site now and also add it to your bookmarks for future visits: http://griffiths.askaboutireland.ie/gv4/gv_family_search_form.php
