Thank you. That is excellent information and I will be following it....this exercise is becoming more and more interesting as I delve into events of about 90 years ago and so many people, such as members of this site, have contributed hugely. Tiny scraps of info have prised open what were previously shut doors.
I have an investigation underway (in Foreign Office archives) into his time as a Bloodhound (Kings Messenger) for the Foreign Office during WW1 and the Russian revolution......and that is really throwing up details I (and the family) never even had any inkling of.
Once this research is completed I will prepare an essay on it and anyone that might be interested,or might have helped in the research, will be welcome to read it.
