The 1850 Babbage Report into public hygiene in Haworth showed that villagers reached an average age of just 25.8 years of age. In this context the Brontës' lifespans seem fairly healthy. Somehow they managed to avoid numerous epidemics of dysentery, cholera, typhus and smallpox, possibly because they lived at the top of Main Street rather than the bottom, so that sewage was draining away from them; possibly because they had access to their own water supply via a well in their back yard.
Branwell died at the age of 31, officially from 'marasmus' (chronic bronchitis), although it is now believed he was probably suffering the same tuberculosis as his sisters Anne and Emily: symptoms had been masked by his alcohol problem. Emily died three months after him, aged 30, from tuberculosis. Anne died, aged 29, five months after Emily, also from tuberculosis. Finally, Charlotte died, aged 38, in 1855, from what was recorded on her death certificate as 'phthisis', or tuberculosis. It is now widely believed, however, that her pregnancy may have caused her death, since she seems to have been suffering excessive morning sickness (hyperemesis gravidarum).
