None of these Deaves' are in my tree, so cannot help you there however, this website may assist you in finding out about family members whose names you already know.
http://familysearch.org/searchAs far as George Walter Deaves, and WW1 goes, his name rings a bell, and may have seen it on a WW1 list in a church some where. All of these lists I have seen with Deaves on I have taken pictures of, so I will raid those as I can find them for you.
Happy New Year, and hope you make many more discoveries!
