The former Miss Peachey is now a memsahib of Lower Bengal. As you probably know, one is not born a memsahib; the dignity is arrived at later, through circumstances, processes, and sometimes through foresight on the part of one’s mamma. It is not so easy to obtain as it used to be. Formerly it was a mere question of facilities for transportation, and the whole matter was arranged, obviously and without criticism, by the operation of the law of supply. The necessary six months’ tossing fortune in a sailing ship made young ladies who were willing to undertake it scarce and valuable, we hear. We are even given to understand that the unclaimed remnant, the few standing over to be more deliberately acquired, after the ball given on board for the facilitation of these matters the night succeeding the ship’s arrival in port, were held to have fallen short of what they reasonably might have expected.
After her marriage to Everard Charles Cotes she spent most of her time between England & India. Duncan had been treated for tuberculosis in 1900, spending the summer out of doors in the fresh air of Simla, as chronicled in On the Other Side of the Latch (1901), published in the United States and Canada as The Crow's Nest. Duncan died of chronic lung disease on 22 July 1922 at Ashtead, Surrey, whence she and her husband had moved in 1921.
In 2016, she was named a National Historic Person on the advice of the Historic Sites and Monuments Board of Canada.
