Hello Tiki...
Was looking through Archway and came across the following....
Imperial Pension Accounts - 1865 to 1891
www.archway.archives.govt.nz/ViewEntity.do?code=17399If you click on
"MORE INFORMATION & INDEX" it describes soldiers in NZ receiving a pension. It covers the right timeframe so maybe George is mentioned.
The finding aid says
"The names of persons receiving pensions that are contained in these registers are indexed into the General Biographical Card Index [BIO 1] located in Archives New Zealand, Wellington Office reading room.Maybe ask for a look-up of the Card Index to see if George is mentioned.

Have also been looking at lots of notations on lots of discharge papers on FindMyPast, cos it's free at the moment

Here's page 4 of George's discharge papers, to which I linked earlier.
THOMAS, George - Page 4 of discharge papers
http://www.rootschat.com/links/0tj6/Famous last words but
as I read it the second notation on George's discharge paper places him in Belfast in 1878 (or 1876...can't quite tell). The bit that looks like
"cau of S.C.J.2 Belfast" is actually shorthand for
"care of the Staff Officer of Pensions, Belfast 2nd District". This is the officer who doles out the pension money to the soldiers living in his district. There were two payment districts in Belfast, thirty three in total in Ireland.
I'll make a reply to your post on the Army board and explain a bit further.

A slight flaw in the Belfast theory is that there doesn't really seem to be a corresponding 1878 or later death in the Belfast area. There is one possible death in 1901 but if he's the chap mentioned in the 1901 Irish census then his census details are wrong. So keep in mind that George may well have returned to the Belfast area but it's as likely he didn't and I've got it wrong.

Would you mind if I started an associated TNA look-up thread on the London board. Not 100% sure what I'm asking for. Something to do with pensions. It could all go horribly wrong so I'd prefer not to involve you directly

Regards
