Hi All Fascinating stuff.
If you're thinking of going further, my gggrandfather was a police officer in Rochdaale and died there in 1881. They may even have creossed paths!
Anyway, the service records are at Lancasahire Record Office, Preston. I wa sent a brilliant two large sheets with birth date, army creer, service dates and forces and more. A couple of pounds for copying and postage.
I actually found it while I was there, and they copied it and sent it on, because they couldn't do it on the normal copier. They sent it nearly straight away though.
I've been told there's a search onl;ine now and you can maybe order too.
I should check it out.
Good hunting.
