Charlotte Bronte's life was very similar to Jane's actually. They both grew up in a orphan-like situation. Charlotte's mother died when she was very young and her father was distant.
Both Charlotte and Jane were sent off to schools for girls where the atmosphere was not very pleasant. In fact, two of Charlotte's sisters died at school from a contagious disease.
Charlotte and her remaining sister were brought home to live immediately after the typhoid outbreak at school which killed her siblings.
She eventually went to another boarding school and then obtained a job as a governess, again, like Jane. She eventually married an elderly friend of her father's. Charlotte became ill from a fever while she was pregnant with her first baby, and died at the relatively young age of 39.
Charlotte published several books and collections of poetry, among them are Villette, Jane Eyre and Shirley. She also wrote tributes to the deaths of her sisters and brother--she outlived them all.
