Birley also notes that the ordinary consul of 201, Lucius Annius Fabianus, was "presumably" his grandson.
[4] Fabianus began as a member of the vigintiviri, a preliminary and required first step toward a gaining entry into the Roman Senate.
[2] He served as military tribune in Legio II Augusta which was stationed in Roman Britain; his service was during the tenure of Quintus Pompeius Falco as governor (118-122).
[3] Following this Fabianus held the typical series of republican magistracies: quaestor, assigned to the city of Rome;[2] then plebeian tribune; and praetor.
After completing his duties as praetor, he was appointed curator of the Via Latina (c. 132-c. 135), then legatus legionis or commander of Legio X Fretensis stationed in Judea (c. 135-c. 138), and finally governor of the imperial province of Dacia from 138 to 141.
