Several records spell his surname 'Dankworth', but from the comments below 'Dankwerth' looks to be the correct spelling.
The page at https://gwulo.com/node/23955 mentions him as 'G.C. Dankworth', but others just use George, so I'm not sure if he had a middle name or not.
Mentioned in several diaries as 'Colonel Doughty'.
