How English is that?
True story (similar but not as dramatic, but true): I recently went to the funeral of a guy I used to work with. I was surprised to see that the order of service named him as Jonathan [Surname], because I'd known him for nearly 30 years as William [Surname]. Fortunately his brother explained it in his eulogy. Apparently my friend was christened William Jonathan [Surname], but it was a bonkers family tradition that they used the middle name, so he was universally known as Jonathan. However, when he went to university, he went to one of those olde worlde Oxford colleges where they paint your name on your room door, and the painter didn't get the memo about the middle name, so he painted William [Surname]. And my friend, being very English, didn't want to make a fuss about it. So he became William. Everybody who had known him prior to university called him Jonathan, and everyone who first met him at university or later called him William. (But he didn't move to Poland.)
