Margaret "Maggie" Brolin (née Sheffield) is the eldest child of Maxwell Sheffield. She is constantly seen bickering with her brother, Brighton, who views her as a nerd. Her relationship with Grace, is generally much warmer. Towards the beginning of the series, Maggie is shy and awkward but, with Fran's influence, she becomes a somewhat popular young woman. Upon meeting Fran, the two bond almost instantly, with Fran behaving like a friend or sister except on the rare occasions that Maggie needs to be disciplined.
