Thanks very much for that. I know Hemingford (only one M) Road very well having played music in the Hemingford Arms for 29 years) also have distant family connections who lived at 87.

So Twickenham appears to be an error and I guess describing him as a Cockney would be questionable as one would be most unlikely to have been able to hear the sound of Bow Bells from Islington/Dalston.
