molly

I'm a little stuck... Click here to teach me more about this clue!

'girl?' is the definition.
(girl's name)

I don't understand the rest of the clue.

(Other definitions for molly that I've seen before include "Seller of cockles, mussels" , "fish" , "Mrs Bloom (Joyce)" , "Diminutive of Mary" , "Flanders? Yes, she kept saying" .)

I've seen this clue in the Evening Standard.
