Still trolling through the Web and found something else of interest. My great-uncle, Frank Hannagan, the brother of my grandfather, Charles, was killed in the First World War.
I've just found a reference to him (!) in a roll of honour of those killed on the 12th October, 1917. (I'm not entirely confident about this date; it may just be when these men were listed.)
He's shown as the son of John and Bridget Hannagan, of 97A, Harrow St., Dunedin, and he's buried in the Tyne Cot cemetery, Belgium. There are several abbreviations which I don't recognise; someone else may be able to help with these. He was Private 24433, and the letters OIR (Otago Infantry Regiment?) and KIA (Kiwi Infantry something?) are alongside his name.
The Roll of Honour takes up innumerable pages of the Web, and is part of someone's enormous genealogical site.
On a separate subject, this is an index to Unassisted Inward Passenger Lists for British, Foreign and New Zealand Ports 1852-1923
It would be interesting to know if any of these people were kin! (It comes from a search done on the public record office of Victoria.)
