[2][1] Losh's papers were destroyed and none of her journals or drawings survive, but her life is described in Henry Lonsdale's The Worthies of Cumberland, published by Routledge in six volumes in 1867–1875.
One of her brothers died young and another had mental disabilities, so that Sara and her sister Katherine became joint heirs of their father's estate.
Her uncle, James Losh, was a barrister in Newcastle, a prominent member of the city's Literary and Philosophical Society, and friends with the poets William Wordsworth, Samuel Taylor Coleridge and Robert Southey.
[1] Sara Losh died at Woodside on 29 March 1853 and was buried in the churchyard of Wreay, where she shares a grave with her sister Katherine.
Losh based her design on an early Christian basilica, with an aisle-less rectangular nave ending in a semicircular apse.
The inside and outside surfaces are decorated with naturalistic stone carvings of fossils, plants and animals, many of them done by William Hindson, son of a local builder.
The churchyard has a likewise Grade II listed mausoleum, built by Losh in 1850 in memory of her sister Katherine.
