What was the name of Jane Eyre's childhood friend at Lowood?

Jane Eyre's childhood friend at Lowood was Helen Burns.

Helen is one of the first important people Jane meets after arriving at Lowood Institution, the harsh charity school for poor and orphaned girls. Older and more philosophical than Jane, Helen endures public punishment and privation with remarkable patience. Her calm Christian worldview contrasts with Jane's fierce sense of injustice.

Helen becomes Jane's moral and emotional role model, alongside the compassionate superintendent Miss Temple. When Jane complains about the cruelty she has suffered at Gateshead, Helen advises her not to let resentment govern her life. Jane does not entirely adopt Helen's passive outlook, but their friendship strongly shapes her character.

Helen later dies of consumption during the school's typhus crisis. Jane visits her at night, and the two girls sleep together in Helen's final hours. Readers sometimes confuse Helen with Diana and Mary Rivers, who become Jane's cousins and friends much later, or with Grace Poole, a servant at Thornfield Hall.
