John and Jonathan are actually two separate names. John derives from Yahweh+chanan (God + is gracious) while Jonathan derives from Yahweh+natan (God + has given). In the US, while it's not unusual for a Jonathan to go by Jon, most Johns are not Jonathans.

Since Murphy has only been called John, I don't know why he was given a different full given name since John is a full given name in itself.
