The girl's name Nina \n(i)-na\ is pronounced NEE-nah, NYNE-ah. It is of Spanish and Hebrew origin, and its meaning is "little girl; great-granddaughter". Also diminutive of Ann (Hebrew) "grace". In Slavic, a short form of names ending with -nina, such as Antonina. Neena is also a Hindi name meaning "pretty eyes". Nina was the name of one of Christopher Columbus's three ships. Ballerina Dame Ninette de Valois.
Nina has 17 variant forms: Neena, Neenah, Nena, Neneh, Neina, Nenna, Ninacska, Nineta, Ninete, Ninetta, Ninette, Ninnette, Ninon, Ninochka, Ninoska, Ninotchka and Nyna.
Also I think that name Gianina is pronounced gee-ah-nee-nah
Could go with a name which I have no idea if it is real or just from a book Nyneave. I wanted that name, but my DH would not have me naming the kids after Robert Jordon characters.
