Maddock is Welsh in Origin.

Maddock is a Welsh given name, ultimately from Madog, built on the element mad “good, fortunate, prosperous” with the affectionate suffix -og. It thus conveys “fortunate one” or “beneficent.” The name is attested across medieval Wales, borne by nobles, bards, and churchmen; the legendary twelfth‑century Prince Madog ab Owain Gwynedd, said by later tradition to have sailed west, enhanced its romantic aura.

In English records the Anglicized forms Madoc and Maddock appear, and the name later became a surname; related variants include Maddocks, Maddox, Maddux, and Maddix. As a modern given name its use is modest but growing in the UK and US, often chosen as an alternative to Maddox with Celtic roots. The Welsh base form Madog remains in use, and Madoc appears in literature, notably Robert Southey’s 1805 epic. Nicknames include Maddy, though many keep the full form. Overall meaning centers on luck, goodness, and generosity.
