Sithy Yi Studio portrait of Sithy Yi and her paternal aunt, Sina Diep, taken in Phnom Penh c. 1974 before the Khmer Rouge took control of Cambodia. The Yi family’s surname prior to the Khmer Rouge was Diep, but the Diep family was marked for execution, so they used Yi instead. From left to right are her cousin, Vithie Diep; her sister, Sithea Yi; her paternal aunt, Sina Diep; her cousin, Vithy Diep; and Sithy Yi.
