 Eva 's autobiography , La <unk> de mi Vida , contains no dates or references to childhood occurrences , and does not list the location of her birth or her name at birth . According to Junín 's civil registry , a birth certificate shows that one María Eva Duarte was born on 7 May 1922 . Her baptismal certificate , however , lists the date of birth as 7 May 1919 under the name Eva María Ibarguren . It is thought that in 1945 the adult Eva Perón created a forgery of her birth certificate for her marriage .
