That's also why you wouldn't (or shouldn't) add 20th century individuals to someone who chronologically seems to have been alive then despite only actually meeting them in the 21st. If it's just a character we meet in the 21st century, and we don't even hear anything about them as children, they don't really belong in the already over-populated 20th.
