Hello Bob,
.There are records of internees in the archives at Kew and I understand from HO records that someone took a census in 1916 of all the internees in the IOM under 45. I sent a request to Kew but they said I would have to go in person to do the search. Then I heard from a researcher there that the records had been lost in the archives. I got the POW # from a lady in the Anglo-German Family History Society so there must be info. somewhere in the UK that would give the background I am looking for. I am waiting for more news from the Society.
Incidentally, Ernest Oswin Ihle's name in the 1901 census was written as Oswin FHLE. He was 24 at that time. Took me ages to find that.
Once again, I appreciate your information and efforts. I'm still searching and used the addresses you gave me but no luck yet.
Robin
