I was checking in-bound links to the Chailey 1914-1918 website and noticed a couple from the For the Fallen website, a site which commemorates "those British and Commonwealth service personnel who laid down their lives for their countries". I think it's a nice idea and so I'm happy to give the site a plug here and also add another link on the main website.
Soldiers Died in The Great War is now accessible on-line with a FREE 14 day trial to Ancestry.co.uk. Alternatively, buy a copy from the Naval and Military Press and conduct your own detailed searches, a facility not currently available via Ancestry. I bought my copy a few years ago now and I've found it invaluable. See N&MP link below.
