Where dose the name young come from?

Question

Where dose the name young come from?

Answer 1

It would be a surname derived from a person being a child of someone else, like "Junior" - e.g. if a man called Bill had a child called Bill then it would be easier to distinguish them by calling the second one "Bill Young" and the surname must have stuck at some point.

Answer 2

old, young

its simply a time fracture
