According to the Wikipedia - "Jack" derived from the pet form of the names Jacob and John, from French Jacques, from Latin Iacobus. Sounds reasonable, given that Jacques and Iacobus in the appropriate tongue sounds very similar to the English "Jack".
The tougher one is how Bill derived from William. No clear explanation that I can find.
Hope this helps.

Jack is usually a nickname for John or Jonathan, although I did have an uncle we called 'Jack' whose name was Jasper.

Yes. Believe it or not, it's John.
President John F. Kennedy's nick name was Jack.
Go figure. I find that odd but it's true.
