Hey I think you're missing someone who sneaks herself into the fight even though she is told to leave. Heres my bio:
Name: Ginny Weasley
Birthdate: August 11, 1981
Age: 16
House: Gryffindor
Ancestry: Pure-blood.
Mother: Molly (Prewett) Weasley.
Father: Arthur Weasley.
Appearance:
Eye color: bright brown
Hair color: Vivid, flaming red, worn as a long mane
Build: the short Weasley variation (like the twins rather than Ron).
Distinguishing features: when her jaw is set, her facial resemblance to Fred and George is striking
Personality: Ginny is a forceful, independent girl who often knows her own mind. She has an energetic, lively personality. Only around Harry Potter, in the first few years of their friendship, was she different. She had a huge crush on Harry, but could not relax around him at all, and became shy and withdrawn in his presence. On the advice of friend Hermione Granger, however, she overcame it, and reasserted her usual self, resulting in her eventually winning the heart of her longtime love. One of the traits Harry was attracted to was that Ginny very rarely wept. She was strong enough to overcome most everything and is extremely smart and creative.
