Have you found any military records for Frederick DERRICK? Do you know the date of his birth or where he was born? I notice that there is a Medal Card of a Frederick G DERRICK who was in the Somerset Light Infantry as a Private No. 9673, then the Hampshire Regiment No 09605 and finally the Oxford & Bucks Light Infantry No 87143. Is this the man you are looking for? The various regiments may have some details which might help.
There is a birth registered in Bristol in 1915 of a James Robert PIPER but can you explain how his adopted perents had the same surname - were they related? When was he adopted?
Have you any idea about when Frank PIPER was killed or where he died? There could well be an article in a newspaper but you do need a litle more information. The British Newspaper Archives is an excellent resource. There would also have been an Inquest which would have been reported.
You could also try looking for the marriage on FreeBMD of a Frank PIPER with a Florence.
