Meaning & History
Dudda is an Old English masculine given name of uncertain origin, possibly derived from a byname meaning "round" or "fat" (from a root similar to Old English duddian 'to wrap' or dūd 'swelling'). The name is attested in Anglo-Saxon England as a nickname or personal name, and is weakly declined in Old English. It is most notably the first element in the place name Dudley (from Dudda + lēag 'clearing'), which survives as a surname and given name today.
