Hermione Jean Granger
I think from what I've heard in the "Chamber of Secrets" when she's making the potion in the bathroom with Harry and Ron, she's sitting criss-cross "applesauce" and you can see her panties.
Yes. Hermione and Ron eventually got married.
Hermione's wand is of Vine wood, which is a light greeny/brown colour...
Hermione Granger is a fictional character, she doesn't exist in real life. The actress who played her in the movies, Emma Watson, is not married.
