About the name
Jack began as a medieval English pet form of John — Hebrew Yochanan, God is gracious — probably by way of Jankin rather than from French Jacques, which is a different name entirely and belongs to James.
It became so ordinary in medieval England that it turned into a common noun several times over: jack of all trades, lumberjack, jack in the box, and the playing card. Few given names have colonised a language this thoroughly. It sits at number 15 in the US and has topped the charts in Britain, Ireland and Australia.
It is already a nickname and does not shorten. One syllable wants length after it (Jack Sebastian, Jack Emmanuel). On our vibe map it is Heirloom with Modern Minimalist bluntness.
