Sisenna was born and raised in Rome being the son of the plebeian general, politician Aulus Gabinius from his wife Lollia[3] from the gens Lollia, perhaps a daughter of Marcus Lollius Palicanus, tribune of the plebs in 71 BC.
Sisenna accompanied his father to Syria[4] in 57 BC, when Gabinius served as a Proconsul in that province.
Sisenna remained in Syria with a few troops, while Gabinius was involved in restoring the Egyptian Greek Pharaoh Ptolemy XII Auletes to his kingdom.
Memmius treated Sisenna with indignity and was not softened by his supplicating posture.
