Thanks 90th and Tim for speedy reply.
I do have a bit of history of J. Milner as a cousin did a lot of research into our family history a few years ago. He was born 5-3-1858 and as far as I know, lied about his age to sign on. The family history I have indicates he served In Gibraltar, Cape Town and then Natal. apparently his medal was made into two brooches at some point and I have no idea of where they are.
However, I have in my possession the original Roll of Honour that was issued to John's family, which lists all the people who were killed at Isandhlwana.
