Anek Nawikamul, a Thai historian, researched the story and found a newspaper article from Siam Praphet newspaper written by K.S.R. Kularb, dated March 10, 1899. It claimed the story of Mae Nak was based on the life of Amdaeng Nak (อำแดงนาก, "Miss Nak"), daughter of a Tambon Phra Khanong leader named Khun Si. Nak died when she was pregnant. Her older children, worried that their father would remarry and their inheritance would be shared with a step-mother, invented the ghost story and threw rocks at passing boats to make people believe Nak's ghost had done it. It also suggested Nak's husband was named "Chum", not Mak.
