SAWright - sorry for the long delay in replying. I have only just noticed your very helpful post.
We must be distantly related, as I share ancestry with the two Daniels sisters.
I am very keen to follow up your suggestion of the Kensington and Chelsea Cemetery, a place I know very well as I use to work in West Ealing and have walked past it many times.
I do not know, however, how to access the burial records for this cemetery. Do you - or indeed any other reader - know where these are kept? It would be great if they were online, though I suspect they are not.
