From PhalkeFactory

Durgabai was Kamalabai's mother. Herself an actress. Not much is known of her. But the title "Durgabai" was later recognised as belonging to a young girl from Kohlapur:

The role of Taramati, played by a male actor in Phalke's version, was this time played by a young Brahmin girl from Kolhapur, Durga Khote, whose phenomenal success attracted others to the profession and lent it respectability. from v.shantaram [1]
