Hi there,
Thanks for the information. I have searched ancestry and have not been able to find a srvice record for your William Fletcher, despite all the details you have provided. He is mentioned in the Medal Roll list - although I don't know what he awarded. It may be worth contacting the old regiment for details of action they were involved in at the time - I come from a service family and I can assure you that all regiments are very proud of their history and most have a wealth of information. I know that the regiment doesn't exist in it's current form but if you google the name details do come up. I did check with the Commonwealth War Graves Commission and there are details of his grave there. I suspect that, going by the information you have given, that you have already done this. Just in case you havn't he died 28th August 1916 and is grave/plot 111.A.10 St Pierre cemetery. It would seem likely that,going by the dates, he may have been part of The Battle of the Somme.Records are updated all the time so something may yet come to light - after all he is on the Medal Roll List so he will have to be there somewhere!
Service records are also available for personnel who served after 1920 and families wishing to request info on deceased soldiers can contact:
Army Personnel Centre,
Historical Disclosures,
Mail Point 555,
Kentigern House,
65 Brown Street,
Glasgow,
G2 8EX
There are certain criteria to be met and a payment but it is a useful address. I am applying for my dad's service record as I know he had a particularly interesting career. Naval and Air Force records are also available.
Sorry I can't be of any more help to you but good luck in your quest.
