Well, 'Zavia' - I'm not sure about 'Zoovia' - has been used as a feminine version of the male name, 'Xavier'. If that is the source, it refers to a place-name in the Basque country of Spain.
Bear in mind, Retarded, that words and names can become corrupted and change through useage. The English surname 'Sinclair' comes from the original 'St Clair'. It seems that it's of Urdu origin, but isn't recognised in any of the Urdu dictionaries or lists of common names. There is also the personal name 'Sufyaan' in Arabic.(Google).
