Molly is a prt form of Mary. Usual English form of Maria, which was the Latin form of the New Testament Greek names Mariam or Maria (the spellings are interchangeable), which were from the Hebrew name Miriam. The meaning is not known for certain, but there are several theories including "sea of bitterness", "rebelliousness", and "wished for child". However it was most likely originally an Egyptian name, perhaps derived in part from mry "beloved" or mr "love". This is the name of several New Testament characters, most importantly Mary the virgin mother of Jesus, and Mary Magdalene. Two queens of England have had this name, as well as a Queen of Scotland, Mary Queen of Scots.

House: Gryffindor

Student Activities: Dumbledore's Army "DA", came up with the name of DA after Fudge's paranoia of Dumbledore creating an army to go against him (OotP).
Played seeker for Griffindor in 1995 and 1996. Then played chaser in 1996 and 1997. Fred, George and Ron were surprised by the information that since the age of six she had been borrowing her brothers brooms to practice flying and the game (OotP).

Most notably would be her crush on Harry Potter. Prone to fits of fangirl behavior (squeaking instead of speaking, blushing red when he's around, and most distrubing of all her whining to her mother I want to go see him "... Mum, oh please..."). Her first appearance was in PS she complained saying she wanted to see the 'the boy who lived' Molly scolds her "...the poor boy isn't something you goggle at in a zoo." It is suspected Ginny sent him a singing Valentine in her first year; however. According to Hermione by her third year she gave up on Harry and moved on. Which proves false in HBP.
Later in OotP when Harry forgets Ginny of her experience of possession by Riddle, she rightly puts him in his place. She does not worry about setting off his temper because as it needs to be said, no matter his temperament.
Also some people will argue the chamber of secrets has has sexual undertones, and something was there between Tom and Ginny. But others will say the scene does have sexual subtext but it was directed at Harry and Tom's has little interest in the opposite sex. But reading the subtext it is more likely the symbolic raping was of the mind and not the body. From Tom summary of the relationship it is entirely possible Ginny become very fond of him, and quite possibly Tom had been practicing his corporal form before he decided he was strong enough to make his attack.
