Hi Clazy2000
Well, this is a new one on me - I thought I was pretty well genned up on Lewes.
Have looked through my database of Lewes burials (St John Sub Castro, All Saints, South Malling, Southover, etc) without success I am afraid - so if anywhere he must be in Lewes Cemetery, opened early 1850's
I have also checked the A2A website for the East Sussex Record Office because, according to their yearly report, they have 85% of their records on line - but again to no avail.
Not very helpful am I, but I bet there are other sussex researchers who can give you a bit more information
