Hi I tried searching on Google and came up with this. Pietermaritzburg's historic central cemetery was sited, as was the norm in Voortrekker dorps, on the edge of the original street layout. The subsequent British takeover of the dorp resulted in the construction of numerous churches, but rather than each having its own adjacent churchyard, one cemetery was used, in 1859 Commercial Road Cemetery was divided into seven denominational compartments straddling Commercial Road.
The Commercial Road Cemetery was in regular use then during the period 1840-1920. This is most likely where he is buried. Having driven past this cemetery in 2011 it has fallen into an appalling state as the city council was bankrupt due to corruption and has spent no money fixing fences etc. As a result vagrants have invaded the cemetery and nobody dares enter the grounds for fear of being robbed. If you go to this link

I found this.
