Rao 2 is an Italian surname derived from the given name Raul.EtymologyRaul is the Italian, Portuguese, and Romanian form of the Germanic name Radulf, which is a cognate of English Ralph. The root of all these names is the Old Norse Ráðúlfr, composed of the elements ráð “counsel” and úlfr “wolf,” thus meaning “counsel-wolf.” The surname Rao likely arose as a patronymic, identifying someone as “the son of Raul” or as being associated with a person named Raul. Alternatively, it may have been derived directly from the given name Raul, possibly carried by an ancestor who was famous or influential.Historical ContextGiven its Italian usage, the surname Rao is concentrated in Italy, particularly in the central and southern regions.
