In September 2014, Michael Morpurgo told Newsround how the lead character in his latest book came to take his name: "At a reading, a little boy came up to me and said: 'I'd love you to use my name in a book'.
"It was Billy Byron, and I'm going to use it. I was looking - I am looking - for a hero's name in the next book that I'm writing."
And so Billy Byron's claim to fame will forever be that he gave his name to a Michael Morpurgo character. But what's yours?
