Michael Pegum, a contributor to this forum, has posted extensively his photographs of Irish war memorials to the following website:
They've reached 761 memorials, and over 20,000 names. Be prepared to find plenty of duplications in terms of people commemorated.
eg Frederick Ewen Falkiner of 57th Squadron, commemorated at Tyne Cot is also recorded on the following Irish memorials:
1914-1918 Memorial Plaque, St Columba's College,Dublin, Ireland;
Solicitors' Memorial, Four Courts, Dublin, Ireland;
Great War Memorial,Unitarian Church, St Stephen's Green, Dublin, Ireland;
Falkiner Memorial,Unitarian Church, St Stephen's Green, Dublin, Ireland;
1937 Reading Room,Trinity College Dublin, Ireland;
Rathfarnham Great War Memorial, RathfarnhamWar Memorial Hall, Dublin, Ireland;
Great War Memorial, Rathfarnham Church,Dublin, Ireland;
1914-1918 Roll of Honour, Rathfarnham Church, Dublin, Ireland.
There's quite a variation in the level of care and attention that many memorials receive across the island of Ireland. Even the example of Fusilier's Arch in Dublin is an interesting one: even at the time of its commission there were those who had supported the Boers, from McBride's Irish Brigade etc through to the Irish-Australian MP for Clare, a chap by the name of Lynch, who had gone on to form a separate Irish unit. On the other hand, you can see developments like the Mayo Peace Park, which is quite inclusive and tries to accommodate the diversity of allegiances and identities.
