Annette Jocelyn Otway-Ruthven

She continued her studies at Girton College, University of Cambridge, writing The King's Secretary and the Signet Office in the XV Century[3] for which she was awarded a PhD.

"[4] A former student, James Lydon (1928–2013), who later became a colleague of Otway-Ruthven at Trinity, claimed of her that 'her contribution to Irish history ... will never be surpassed'.

[6] Otway-Ruthven's area of particular interest was Ireland in the twelfth century and the impact on the country of the arrival of the Anglo-Normans.

[7] She translated the Cambridgeshire Domesday Book in 1941 and the Liber Primus Kilkenniensis.,[8] she published Dowdall deeds with Charles McNeill in 1960 and brought a calendar of the Talbot de Malahide papers close to completion.

The college is also home to the Castle-Otway Harp, an eighteenth-century Irish musical instrument which, although it has no known association with the family, was in Castle Otway from the mid nineteenth century.
