History & Origin
Maddock anglicizes the Welsh Madoc, built on mad, 'fortunate' or 'generous.' Long borne as a surname, it re-entered use as a first name in the twenty-first-century taste for sturdy Celtic and surname-style boys' names.
It was never common as a given name, reaching only about fifteen boys a year at its peak in the twenty-tens. A boy named Maddock then is still young, his name tied to a Welsh legend of a westward voyage.
