The comment by Mary A to keep an open mind regarding Edward and Warlingham may turn out to be prophetic.
Birth Registered.
Edward Albert FULLER,Godstone,Sept Qt,1882,Vol 2A,Page 191
Warlingham is within Godstone Reg.Dist.
This may be further reinforced by a Marriage Registration.
Edward Albert Fuller,Croydon,Dec Qt,1903,Vol 2A,Page 500.
The only other name on the FreeBMD page is Eliza PITT.
There are several other possibilities for these siblings marriages at Croydon.
Hope this helps.
Dave.
