K C P Greenson. Causing the body to be cremated.
Did the person die in a hospital? Quite often I've seen informants shown as Mr X, nurse in charge or similar, causing the body to be buried when someone has died in a hospital, mental hospital or workhouse. Perhaps this person wanted to be cremated. The only other explanation is that for a cremation you need the signatures of 2 doctors so perhaps K C P Greenson was one of the doctors.
