Hiya!!
Just stumbled across the thread while looking for 'Second Chatham Depot Battalion Chatham Barracks Number 1' - I also have a 1861 Census question

On RG 9 483 (page 10 of the census - line 10 -14) the Chapple family are listed.
J Chapple Private Army aged 40 born in Ireland
R Chapple Wife aged 29 born in Ireland
J Chapple son aged 8 born in Ireland
S Chapple daughter aged 3 born in Chatham, Kent
M A Chapple (Mary Ann) daughter aged 2 born in Gibraltar
I've done a magnitude of searching but keep coming up with multiple answers or none at all!
If J Chapple was based in Gibraltar when Mary Ann was born, would it be possible to narrow down the regiment he was in and from your previous answer - would he have then gone on to India?
His eldest daughter (1 year older than Mary Ann) is listed as being born in Chatham, Kent - How long were they posted and would this possibly be his second stay in the barracks?
In later census searches for Mary Ann, she married a Michael G Gallagher and lives with an Uncle called John Frarey/ John Tracy (1891 and 1901). I have taken this into account for R Chapple as a possible maiden name but still come up with nothing.
Absolutely anything to add to the tree would be greatly appreciated!
Thankyou!!
