Agnes Grey: Agnes Grey is the debut novel of English author Anne Brontë (writing under the pen name of Acton Bell), first published in December 1847, and republished in a second edition in 1850.  The novel follows Agnes Grey, a governess, as she works within families of the English gentry.  Scholarship and comments by Anne's sister Charlotte Brontë suggest the novel is largely based on Anne Brontë's own experiences as a governess for five years.  Like her sister Charlotte's novel "Jane Eyre", it addresses what the precarious position of governess entailed and how it affected a young woman.

Jane Eyre: Jane Eyre (originally published as Jane Eyre: An Autobiography) is a novel by English writer Charlotte Brontë.  It was published on 16 October 1847, by Smith, Elder & Co. of London, England, under the pen name "Currer Bell".  The first American edition was published the following year by Harper & Brothers of New York.

Emily Brontë: Emily Jane Brontë ( , "commonly" ; 30 July 1818 – 19 December 1848) was an English novelist and poet who is best known for her only novel, "Wuthering Heights", now considered a classic of English literature.  Emily was the third-eldest of the four surviving Brontë siblings, between the youngest Anne and her brother Branwell.  She wrote under the pen name Ellis Bell.

Katherine Frank: Katherine Frank is a noted American author and biographer, now living in England.

Brontë family: The Brontës ( , commonly ) were a nineteenth-century literary family associated with the village of Haworth in the West Riding of Yorkshire, England.  The sisters, Charlotte (1816–1855), Emily (1818–1848), and Anne (1820–1849), are well known as poets and novelists.  Like many contemporary female writers, they originally published their poems and novels under male pseudonyms: Currer, Ellis, and Acton Bell.  Their stories immediately attracted attention for their passion and originality.  Charlotte's "Jane Eyre" was the first to know success, while Emily's "Wuthering Heights", Anne's "The Tenant of Wildfell Hall" and other works were later to be accepted as masterpieces of literature.

Poems by Currer, Ellis, and Acton Bell: Poems by Currer, Ellis, and Acton Bell was a volume of poetry published jointly by the three Brontë sisters, Charlotte, Emily and Anne in 1846 (see 1846 in poetry), and their first work to ever go in print.  To evade contemporary prejudice against female writers, the Brontë sisters adopted masculine first names.  All three retained the first letter of their first names: Charlotte became "Currer Bell", Anne became "Acton Bell", and Emily became "Ellis Bell".  The book was printed by Aylott and Jones, from London.  The first edition failed to attract interest, with only two copies being sold.  However, the sisters decided to continue writing for publication and began work on their first novels, which became commercial successes.  Following the success of Charlotte's "Jane Eyre" in 1848, and after the deaths of Emily and Anne, the second edition of this book (printed in 1850 by Smith & Elder) fared much better, with Charlotte's additions of previously unpublished poetry by her two late sisters.  It is believed that there are fewer than ten copies in existence with the Aylott and Jones' title-page.

The Tenant of Wildfell Hall: The Tenant of Wildfell Hall is the second and final novel by the English author Anne Brontë.  It was first published in 1848 under the pseudonym Acton Bell.  Probably the most shocking of the Brontës' novels, it had an instant and phenomenal success, but after Anne's death her sister Charlotte prevented its re-publication.

Druid Heights: Druid Heights was a bohemian community on the southwest flank of Mount Tamalpais in Marin County, California, about a mile from the Pacific Ocean.  It was founded by carpenter Roger Somers and poet Elsa Gidlow in 1954 on five acres of a former chicken ranch.  The name Druid Heights was given to the acreage in honor of two lesbian writers, the revolutionary and teacher of Irish lore, Ella Young (the Druid), and Emily Bronte (author of "Wuthering Heights").

Charlotte Brontë: Charlotte Brontë ( , "commonly" ; 21 April 1816 – 31 March 1855) was an English novelist and poet, the eldest of the three Brontë sisters who survived into adulthood and whose novels have become classics of English literature.  She first published her works (including her best known novel, "Jane Eyre") under the pen name Currer Bell.
