County Carlow's Great War Memorial Register has been made available as a downloadable pdf here.
Some 400-names are included on register, listed alphabetically by town of origin. Each entry gives the soldier's name and regimental details, date of death and, sometimes, age.
A few entries have additional identifying information which will be useful to researchers trying to connect familial members eg Daniel and Patrick Conroy, who were aged 34 and 37 respectively and were both privates in the Royal Dublin Fusiliers but died on different dates in 1916, are identified as brothers.
