Tagore was the eldest of three children and had two younger sisters, the late Oindrila Kunda Tagore and Romila Sen . Oindrila was the first in the family to act in a film, and the only role she ever played was that of "Mini," the child character (but a central character) in Tapan Sinha's film Kabuliwala (1957). In adulthood, she became an international bridge player. Her other sister, Romila Sen, is married to Nikhil Sen, a corporate honcho who served as Chief Operating Officer of Britannia Industries for several years.
