Women BAs in India and England

Wiki tells us that from the University of Calcutta "Kadambini Ganguly and Chandramukhi Basu became the first lady graduates of the country in 1882."

Elsewhere (emphasis added)

Henry and Eleanor Sidgwick set up Newnham College, Cambridge, in 1880. Mary Hamilton wrote about her experience at Newnham College in the early 1900s in her book, Remembering Good Friends.

Eleanor Sidgwick and Henry Sidgwick had, throughout their life together, chosen to give their time to college. She had renounced mathematical research of a very high order in order to come and assist Miss Clough in the early days. Early in their married life, which was a perfect partnership, they gave up their own home to come and live in Newnham… They enjoyed the triumph of 1881 in the passing of the Senate of the Graces admitting women to the right of sitting for Tripos examinations and being placed on the lists, the struggle for full recognition - the granting of degrees, and admission to membership of the University was entering on a long, slow phase, with no end in sight. (It was in fact to take forty years and a world war to persuade the authorities to grant degrees to women.)

Oxford tells us:  (see this also)

Women were not admitted to membership of the University until 1920, although they had been allowed to sit some University examinations and attend lectures for over forty years by that date. It was thanks to individual initiatives, and the pioneering work of the Association for Promoting the Higher Education of Women (AEW) that women's colleges came to be established in Oxford. Lady Margaret Hall and Somerville opened in 1879, followed by St Hugh's in 1886 and St Hilda's in 1893. St Anne's, which in 1952 was the last of the women's colleges to be incorporated by Royal Charter, originated as the Society of Oxford Home Students, catering for women students who lived with private families in Oxford while attending courses organised by the AEW. The five women's societies were granted full collegiate status in 1959.
