I have found various ancestors in London, and particularly in the area around the East End, had their children baptised in a CofE church but buried them in a non-conformist burial ground. I don't think this necessarily had anything to do with religious beliefs, it's quite possible that the burial fees were lower than for CofE burials and thus were used for this reason.
I also have some families that intermittently used non-conformist chapels to baptise children when the previous and subsequent child was baptised in the local CofE, this could be for financial reasons if the fees were lower of simply they couldn't get them baptised in the CofE church when they wanted to.
It's quite likely these burials are yours but you would need to check the possibilty they related to other families of the same name. Unfortunately many non-conformist burial grounds in that area did not list ages on burials even after 1813 when the CofE parishes were following the change in style of registers.
