Nagagua

Unfortunately, the name "Naguagua" does not qualify as either Slavic or Russian, in the form it is presented. It does not appear in historical or literary sources as a masculine Russian name. If you meant another name which might sound similar or share origins, please clarify. For example, the name "Naga" originates from Indian culture, while "Guo" could be a variation of a Chinese name.
