Thanks to Chris Paton for the following piece of news:
The National Archives at Kew has announced that 20,000 records of soldiers who discharged to pension at Kilmainham Hospital in Dublin have now been catalogued from WO119, and can be viewed on the archive's main catalogue. The period covered is 1783-1822, and includes soldiers from all over the British isles who ended their careers pensioned in Ireland, rather than Chelsea. The work was carried out by the Friends of he National Archives.
These records are in fact being digitised at present by FindmyPast, which has already made TNA's Chelsea pension records available online.
