[4] Winkworth translated the memoir and essays of German theologian Barthold Georg Niebuhr, in Life and Letters (1851 and 1852).
[5] She followed with more German religious literature, with translations of the Theologia Germanica (1854)[6] and twenty-five sermons of medieval mystic Johannes Tauler (1858).
Her last notable publications were a translation of Bunsen's God in History (1868-1870), and an 1883 memorial edition of her sister's writings, after Catherine Winkworth's death in 1878.
She invested in housing at Dowry Square, built more units for low-income renters at Jacob's Well, and managed a sanitary mission.
In the year 2000 a blue plaque was installed, marking the home of Catherine and Susanna Winkworth in Cornwallis Crescent, Bristol.
