I would also like to suggest a link for the Irish Genealogy website (which is free) on www.irishgenealogy.ie. It gives births 1864 to 1918, marriages (1845 to 1943) and deaths (1864 to 1968). Church records are also available. This is an invaluable website for anyone doing family tree research. I would also like to suggest that the Irish Census records are also available for 1901 and 1911. This is available at www.census.nationalarchives.ie (free of charge).
Anyone who has County Monaghan ancestors will find this link useful. Published by Monaghan County Council and Library Services it gives tips and advice on how to trace your ancestors.
