Esther John was a Pakistani nurse born as Qamar Zia in 1929 during the British Raj. After converting to Presbyterian Christianity following her studies at a Christian school, she moved to Pakistan in 1947. Seeking to practice her faith freely, she adopted a new name and worked in various capacities, including serving at a mission hospital. Her commitment to Christian evangelism in the villages near Chichawatni eventually led to her death in 1960, resulting in her recognition as a martyr.
