What was the behavior of Bertram's children towards Fanny? What did Fanny feel about her cousins?

After arriving at Mansfield Park, Fanny's cousins, Maria and Julia, castigate her for her poor, unfashionable clothing, her inability to speak French, and her lack of refined manners. Mrs. Norris constantly attempts to keep Fanny down, and completely ignores the possibility that the girl might be missing her family. One day, Edmund finds young Fanny crying alone and comforts her. Fanny immediately feels better, and quickly develops a strong attachment to Edmund. To the girls' horror, Fanny does not exhibit any inclination towards musical instruction or drawing, but the adults seem pleased with her quiet, unobtrusive demeanor. Sir Thomas procures a position in the Navy for Fanny's favorite brother, William.
