Well!!!
Firstly, just to reiterate, the Indian Mutiny casualty roll i have is a book(indexed by regiment), therefore it isn't fully searchable so unless you have a regiment or idea of one then i would have to spend an hour going through it for each person, im nice

but not that nice

sorry.
The Crimean casualty list is online
http://hometown.aol.co.uk/heatherasplin/home2.htmlI have the book , but now it is online, i use that instead,for the same reason as above. So you can double check it if you want.
Here we go:(not good results)
NMcS : none of them listed
Tigger: no Chesters listed in the 84th
Bibbypj: No James Bibbys there are some others if interested
ClazyAunt: Got a Gunner John Saunders(RA) slightly wounded at Lucknow 9/3/1858 and 11/3/1858
Mountain Man: not listed , see above link
Rosemay: No Roger Woods in medal list or casualty roll
Andreajs: not listed, see above link
malcolm1: not listed, see above link
criggy: thanks Mick

saxonw: welcome, the 7th dragoons aren't listed in the book, they must be under another regiment.
Nothing useful, sorry people.
