Priscilla Hannah Peckover (27 October 1833 – 8 September 1931) was an English Quaker, pacifist and linguist from a prosperous banking family.

[5] The Auxiliary approved her proposal for a short declaration, "I believe all war to be contrary to the mind of Christ ... and am desirous to do what I can to further the cause of Peace", to be signed by "women of all ranks".

[9] Her background led her to use collaborative and conciliatory methods, in contrast to the more defensive and less cooperative approach of the Peace Society.

Peckover played a central role in organizing a new ladies auxiliary of the Peace Society that was launched on 12 July 1882.

Its Ladies' Peace Association was much more dynamic, and claimed 9,217 members by the summer of 1885, of which 4,000 belonged to Peckover's Wisbech group.

[16] Peckover made contact with groups in France, Germany, Scandinavia, Italy, Switzerland, Spain, and Denmark.

[5] Louis Barnier of Nîmes, who founded the precursor of the French Peace Through Law Association in 1887, met Peckover while he was a student in England.

[1] Peckover launched the quarterly Peace and Goodwill: a Sequel to the Olive Leaf in 1882, and edited and funded the journal for the rest of her life.

It mainly discussed absolute Christian pacifism and the peace movement, but also included criticism of the oppressive practices of the British Empire.

[16] Peckover was also President of the Ladies' Temperance Committee, which distributed literature in Wisbech and the neighboring suburb of Walsoken.

[3] Priscilla and her sister Algerina Peckover (1841–1927) provided financial assistance for the preparation and publication in Britain in 1926 of an Esperanto version of the Bible, the 'Londona Biblio'.
