Who, among the following women writers, famously imagined the plight of Shakespeare’s sister ?

In A Room of One's Own (1929) Virginia Woolf imagines Judith Shakespeare, a sister as gifted as William, who is denied education and independence and dies without writing a word. The story shows how the lack of money, privacy and freedom has kept women's genius from expression. George Eliot, Iris Murdoch and Frances Burney were women novelists, but none created this thought experiment.
