Can not find a birth for George Herbert Giles He was born in 1880 Surrey but his birth seems to have disappeared
I have everything else
I can't find it either. As a side note: have you noticed that his father is actually George William, not George Walter?
This looks like him:
England, Births and Christenings, 1538-1975.Salt Lake City, Utah: FamilySearch, 2013.
Herbert, the son is registered :
In 1939 Herbert G Giles ( born 3 May 1910 ) and Myfanwy ( born 7 Jan 1914 ) are at 68a Abingdon Street, Burnham on Sea, Somerset. He is an Auxilliary Postman and Night Telephonist. She is a Shop Assistant.
The 1911 census has Reginald born in Williton, so this is probably his birth reg ( no entry in Mother's maiden name column ):
HIGHBRIDGE, The funeral took place at Highbridge of George Herbert Giles, of Highbridge, who was accidentally killed whilst working at Messrs A. G. Pitts and Co's brickyard. Mr S. Saunders, (director) and Mr W J Tackle (manager’) were present, in addition to all the employees, a number of whom were bearers. The service was St. Peter's Church, Huntspill.
