The Bronte Graves
1) the Bronte family are not buried in the churchyard, but in a vault beneath the church itself, in the south-east corner, near the Bronte chapel. Buried here are the Revd. Patrick Bronte's wife Maria (1783-1821), his two eldest daughters Maria (1814-1825) and Elizabeth (1815-1825), his sister-in-law, Elizabeth Branwell (1776-1842), his only son Branwell (1817-1848), his daughters the novelists Emily (1818-1848) and Charlotte (1816-1855), and finally Patrick himself (1777-1861), who outlived all his family. The youngest, Anne (1820-1849) died at Scarborough on the Yorkshire coast and is buried in St. Mary's churchyard, overlooking the sea.
2) The Brown family memorial
John Brown (1804-1855), the Haworth sexton and close friend of Branwell Bronte is buried here along with his daughter, Martha Brown (1828-1880) who came to serve at the parsonage as a young girl and remained until the last member of the family, Patrick Bronte, died in 1861. The Brown memorial is close to the garden wall at the side of the Parsonage.
3) Tabby's grave
Tabitha Aykroyd, or "Tabby" as she was known, was the Bronte family's faithful servant for thirty years. She worked for them from 1825 until her death at the age of eighty-four in 1855. Tabby is buried close to the wall at the bottom of the Parsonage garden.
