Hello Glen,
The service records for other ranks, who served in the RFC in WWI are quite scarce. I had tried to locate his service and pension records through Ancestry, but without any luck.
Here are the details that I have on Cpl. 8183 George Henry FURNEAUX, born 11 Feb. 1883 in Torquay. He died 4 Jan 1918 and is buried at Doullens Comm. Cemetery Ext. No. 1. On his death certificate it gives his rank as Corporal 1 A.D. [which I think means No1 Air Depot at St. Omer, France], he died of Pneumonia.
If you can find any of his records, I should be very grateful,
thank you,
Brian
