You're most welcome.
If anyone can help me find any record after the beginning of WWi for Peter KREIN, born Germany, settled in England before 1901, who was interned somewhere in Britain, I'd be thrilled. In early 1914 he was a 48-year-old master baker living in Camden. There is no record of him at Isle of Man; and Kew is thousands of miles and a big puddle of salty water away, alas. Perhaps I'll find him somewhere in my own bibliography, once I have time to read it all!
So much research, so little time!
