Do you think that Kit Harington is the real name of the 'Game of Thrones' star? If so, you know nothing, Jon Snow! It's not far off though; the actor is really called Christopher Catesby Harington. Don't worry if you didn't know that; he didn't actually know his real name himself until he was eleven years old and saw it on a school register!
Even though he was born 'Christopher', his own parents called him 'Kit' as a nickname from the moment he was born, and he never had reason to believe any differently. That's apparently not a rare thing within his family; his brother goes by John but was actually born Jack. Maybe Mr. and Mrs. Harington should have waited a little longer before deciding on final names for their offspring! Unfortunately, we have no information as to where the delightfully unusual middle name comes from.
