Things are changing in the world of online resources for Irish genealogical research. The availablility of online searchable records or indexes means that people who had given up all hope of finding ancestors, have been given new opportunities. I list the three main online sources below:

• Griffith’s Valuation (survey taken of heads of households circa 1850) at:
  http://griffiths.askaboutireland.ie/gv4/gv_family_search_form.php

• 1901 and 1911 Census records is online for some counties but all counties will be represented soon at: http://www.census.nationalarchives.ie/

• Irish Civil Records Index from 1864 at:
  http://pilot.familysearch.org/recordsearch/start.html#c=1408347;p=collectionDetails;t=searchable

If anyone can name others, please comment and I will add them.
