I have a London death certificate for a James Miller aged 43 in 1882. After paying for it, I discovered this man was not the James Miller I was looking for. If he is the one you are looking for, I am happy to pass on this certificate to save you the fee. He died in the Holborn district (Amwell sub-district) on 7 August 1882. The address looks like 1 Great Percy St. He was a surgeon. A G.V. Foster of the same address was the informant.
