French historian Christian Settipani gives the parents of Gordian I as Marcus Antonius (b. ca 135), tr. pl., praet. des., and wife Sempronia Romana (b. ca 140), daughter of Titus Flavius Sempronius Aquila (b. ca 115), Secretarius ab epistulis Graecis, and wife Claudia (b. ca 120), daughter of an unknown father and wife Claudia Tisamenis (b. ca 100), sister of Herodes Atticus.[4] It seems therefore that the person who was related to Herodes Atticus was Gordian I's mother or grandmother and not his wife.[8] Also according to the Augustan History, his wife was a Roman woman called Fabia Orestilla,[2] born circa 165, who the Augustan History claims was a descendant of Roman Emperors Antoninus Pius and Marcus Aurelius through her father Fulvus Antoninus.[2] Modern historians have dismissed this name and her information as false.
