I'm first seeing this thread over 12 years after the original post, but came across it yesterday whilst researching this family because I know Deberiot's grandson - he is the 3rd generation (at least) of string players in the Green family!
I have found Deberiot through all the censuses from 1861 to 1911, and then traced him right up to his death in 1935 - he appears in most of the London electoral registers for the 1920s with his wife Annie and son Horace.
Deberiots' parents, Jabez Green and Eliza Vernon, were married on 28 Nov 1836 at St Mary's, Lambeth.
