Born in the Karadat Mariam area of Baghdad, Iraq in 1937 to an Chaldean family, Auchi attended Al Mansoor Primary School and Baghdad College High School, before going on to study at Baghdad's Mustansiriyah University. He married his wife Ibtisam in 1963, and together they have 3 daughters and 1 son, born in 1964 and 1972 respectively. In 1979, he and his family fled to London following an extortion attempt by an enforcer for Barzan Ibrahim al-Tikriti. Six years later, Auchi's younger brother Naseer was hanged by the Baathist regime after discovering the extent of al-Tikriti's corruption. Auchi became a British citizen in 1989 and currently resides in London. He and his wife have aimed to promote inter-faith dialogue, unity among Arab states, and to build bridges between the West and the Arab world through charitable and humanitarian work, for which Auchi has been recognised.
