Yes, he is part of a vast clan known as the Hyuugas, they are all blood relatives.
Hinata has a younger sister named Hanabi in naruto. This is revealed in the finals of the chuunin exams when Hinata's father is talking with her while Naruto and Neji are fighting.
No they are just cousins. Hinata and Neji's fathers were twin brothers, therefore making Hinata's father Neji's uncle and Neji's father Hinata's uncle. Making them cousins. Correction Neji and Hinata's fathers are identical twin brothers meaning Hinata and neji are socially cousins but biologically half siblings
Neji is stronger.
His dad's name is Hizashi Hyuuga, his uncle's name is Hiashi Hyuuga, and his cousin's names are Hinata and Hanabi. P.S. It's spelled Hyuuga
Throughout the series I think there has been no hints of Hinata's mother though I think in the flash back of Neji during Naruto vs. Neji Chunin Exams she is beside Hiashi but there is no evident proof of Hinata's mother dying. But there are some evidents where when they took a family picture together when Hanabi was a baby that her mother died shortly after the picture was took.
No, but Neji does have a crush on her.
Because Neji actually had romantic feelings for Hinata.
Hinata lives in the Huyuaga family, with her cousin Neji.
well neji could be considered her brother kind of. Neji IS Hinata's half brother due to both of there Fathers are IDENTICAl twins.For proof search Neji's History on Wikipedia. But technically he is considered hinata's cousin.
sometimes
i think Hinata
Neji doesn't have to marry Hinata. Where did you hear they were going to get married at? They're cousins so no.
