What is the meaning of the name Madawg ?

Madawg is English in Origin.

Madawg is a medieval Welsh form of Madog, often anglicized as Madoc. It derives from Welsh mad “fortunate, good, kind” plus the adjectival suffix -og/-awg, yielding the sense “the fortunate one” or “beneficent.” The spelling with -awg reflects Middle Welsh orthography; the final g is always hard.

The name appears across early Welsh poetry, triads, and genealogies, and is most famously borne in legend by Madog ab Owain Gwynedd, a 12th‑century prince reputed to have sailed west to unknown lands - a tale later invoked in Tudor and Elizabethan times. While uncommon as a modern given name, it persists in place‑names and has seeded a family of surnames: Maddock, Maddocks, Maddox, Maddux, and Maddix. Variants include Madog (standard Welsh), Madoc (English), Madawc/Madawg (medieval spellings), and the patronymic forms Madog ap/ab. Usage today is rare but attractive to those seeking a strongly Welsh, adventurous choice.
