Thanks for the information, sorry I have not answered sooner.
I would say that it is definitely the man I am after, I have found him on the 1901 and 1911 census, also I have found an entry in the London Gazette for him relinquishing his commission due to ill health, all I need now would be to find someone going to Kew to do a look up for me as I cannot get away from work.
This is all tied into the fact I recently added his medals to my collection of Royal Sussex WW1 medals, he was awarded the standard pair of British War & Victory Medals, the Mic i have found also and his entitlement to the SWB No 290653 (unfortunately not included).
Again many thanks for the help
Roy
