This paper shares the untold stories of three missions to the deaf and mute in India and Sri Lanka. Prior to Indian independence, three of the first schools in the country focused in the deaf were founded by the women of the Church of England Zenana Missionary Society (CEZMS). Their locations were Palamcottah, in Tirunelveli, India, Mylapore, in Chennai, India, and Kaitadi, near Jaffna, Sri Lanka. Each of these schools has adapted over time and continues to serve deaf students today with local leadership. there is a wider interest in the factors which allowed missionary institutions to transition to local leadership and thus survive and thrive in a post-colonial world. These missions include: the Florence Swainson Deaf School in Tirunelveli, India, the Church of South India (CSI) Higher Secondary School for the Deaf in Chennai, India, and the Ceylon School for the Deaf and Blind in Sri Lanka.
