In early development, Dr Crusher originally had a daughter named Leslie Crusher. The point of that character wasn't very well-defined before she was turned into a brilliant male wunderkind named Wesley by a man whose full name was Eugene Wesley Roddenberry. In other words, the point of the character was that an aging egomaniac wanted a self-insert character whose traits are that he's special, he's a genius, and that he's frequently misunderstood and let down by all the dolts who surround him.
