If you're on Facebook you may have seen a recent posting by the Irish Genealogical Research Society. (Their site, IrishAncestors, was among GenealogyInTime's top 100 genealogy websites.) News to me were five free-to-view resources on the IGRS site:

• The Irish Genealogist Database
• The IGRS Early Irish Marriage Finder
• The Irish in Spain
• Drumcondra civil parish, County Meath; an 1871 census fragment
• Elphin Diocesan Census 1749, Indexes
