good question, Howard :-) I phrased that badly, in order to avoid unnecessary complications and details of my private life. Suffice it to say that I got the information from, among others, my mother, who came from Prague and whose maiden name, translated, was that of a type of orange. She had many friends with such names, including Max Brod (a variant of the word for 'bread') and also Franz Kafka. Here in England I also know people whose names are clearly anglicised versions of German names given to their families at the time in question. As regards your specific question, I am 62. Cheers
