according to Manx Sun of 5 june 1850 a company of the 52nd regiment was about to replace a company of the 62nd regiment which regiment was due to be posted somewhere I didnt note! - I recall some comment but can't vouche for it that the Castletown garrison, apart from a handful of long term barrack sergeants etc was formed from a company of the regiment either at Preston or at Carlisle (the latter I think seemed to crop up more frequently than the former).
Some tedious reading thru newspapers might bring up the sequence - anyone with a spare week to spend trying to use the aweful scratched films in the Manx Museum please volunteer ?
