Anne Dacre Howard, Countess of Arundel (1557–1630) was connected by birth to the prominent Dacre family and by marriage to the powerful Howards. She was formally reconciled to the Catholic Church in the early 1580s. Her husband, St. Philip Howard (1557–1595), was also a Catholic, converting in the fall of 1584. He was imprisoned in the Tower in April 1585 after an attempt to flee Protestant England; the convictions, fines, and seizure of property following his Star Chamber trial of 1586 and his treason trial in 1589 left his wife in precarious straits. Despite the difficulties she faced, Anne Howard steered her family and her husband’s heir, Thomas Howard, towards stability. She sheltered Catholic priests for nearly fifty years, from the early 1580s to her death, most famously supporting the poet and martyr St. Robert Southwell SJ. As a Catholic female head of household she made substantial contributions to English Jesuits, yet her patronage and particularly her medical services were not constrained by religious boundaries. Most remarkably, perhaps, she also collaborated with a Jesuit biographer to produce two biographies of herself and of her husband, who would be canonized in 1970. Her substantive correspondence among family members and other contemporaries remains to be fully explored, as does her full record of contributions to international religious and political networks.
