Margaret Haydock continued the long tradition of her family in standing firm for her Faith during the Penal Period against Catholics in England.
Hostilities related to the Flanders Campaign precipitated by the French Revolution forced evacuation of the convent in 1794.
Sister Stanislaus and her fellow nuns left on 28 June that year and settled in Hammersmith Convent near London, after a perilous escape over land and water via Breda, Rotterdam and Gravesend.
After one year there, they settled in St Monica's Priory, Spetisbury in Blandford, Dorsetshire,[3] where they began a boarding school for girls.
Known as Peggy by her family, Sr. Stanislaus frequently wrote to her brothers, although failing eyesight in her later years required her to have others write on her behalf.
