Margery Fenworthy

Margery Fenworthy is a student at St Clare's School. She first appears in The O'Sullivan Twins.

Backstory
Margery's mother died when she was little. Her father remarried and her stepmother and her didn't like each other. Her father also favoured his stepsons because he had always wanted boys, making Margery feel like she wasn't wanted. She was sent away to boarding school after being rude and unpleasant, and continued being rude and unpleasant there. She is expelled from six schools before coming to St Clare's, one of which being St Hilda's School.

The O'Sullivan Twins
Margery keeps herself to herself at St Clare's, is poor at her work and gives short, rude answers. Janet Robins suspects she has some sort of past. Margery is discovered at being excellent at games and gym. When Erica is sent to Coventry, Margery is the only one who speaks to her, not caring for the girls' rules. The girls decide to make more of an effort with Margery, praising her for her gym and games, but two weeks later, the Big Row happens. After that, no-one wants to be friendly with Margery, and they all turn on her. Margery is playing in a school match, but is not cheered either time she scores a goal, all because Pat O'Sullivan reminds everyone that Margery is in Coventry. Erica begins to play tricks on Pat, and everyone assumes Margery is responsible, and they don't believe her when she protests her innocence. At half-term, Pat, Isabel and Alison O'Sullivan meet their friend Pamela Holding, who tells them of Margery's past and disgrace. Alison spills the beans after a second trick is played on Pat. The sickbay catches fire, and Erica is trapped inside, so Margery goes to rescue her. She saves Erica, but breaks her leg. Erica confesses to the pranks and is sent away from St Clare's. Pat, Isabel and Lucy Oriell write to Mr Fenworthy praising Margery, who is thrilled. After Lucy's father is injured and Lucy may have to leave St Clare's, Margery finds help for her and a way to stay on, through a scholarship.
