Yes, it's a very long time since anything was posted on here, but as a result of my daughter Abby finding a website called Shadow Battalion, we discovered that according to their records not only was Frank Hannagan (my great-uncle) present during the First World War - he died in 1917 at Passchendaele - but two other relatives appear to have served there at some point: Albert Alexander Hannagan, and John Blaney Francis Hannagan.
Albert was my great grandfather's nephew - the son of Charles Hannagan Senior (I've listed him as 'senior' because my own grandfather was also Charles). John Hannagan was Albert's brother.
