Louisa Sarah Ann Parr (née Taylor; c. 1848 – 2 November 1903) was a British writer who published some of her work under the name Mrs Olinthus Lobb.

It was published in English in 1868 in the evangelical magazine Good Words as "How it all happened",[2][1] and the story was soon reprinted in French and later in German.

[1] This novel recalled her nautical childhood; it was set in Cornwall where the protagonist "Adam" lives and smuggles.

[4] The stories in this novel were based on fact as she re-used situations recorded in the History of Polperro which was written by Jonathan Couch in 1871.

[1] In 1897, Women Novelists of Queen Victoria's Reign was published and this included a short biography written by Parr about her fellow writer Dinah Mulock Craik.
