So speaking of motivation, how does every child in a family group up to be a famous writer or poet?

The Bronte sisters: Anne, Emily, and Charlotte all became famous writers separately. Charlotte of course wrote Jane Eyre, while Anne is famous for The Tenant of Widfeld Hall, and Emily for Wuthering Heights. Their brother Branwell was also a respected writer and even painted the above painting.

Back to how they became great writers: During their childhood they would all work together and write stories together with collaborative imagination. Furthermore, the deaths of other sisters and their mother brought the four siblings even closer together and influenced their writing.

But in the end it all started with their father, Patrick Bronte, a respected theologian and writer in his own right

Patrick personally took care of the children's education and encouraged them to read as much as possible, he also almost exclusively brought the girls up after their mother died.

As for a song:

I would use this song from The Coen Brother's great movie O Brother Where Art Thou in a contemporary Jane Eyre set in old world Mississippi or Lousiana in a truly dark portrayal of Childhood and love. This song represent Jane's desire to escape to nature.
