ルキウス・コルネリウス・キンナ
Pompeius’ maternal grandparents were both direct descendants of Pompeia, the daughter of triumvir Pompey (Gnaeus Pompeius Magnus) from his third marriage to Mucia Tertia. His maternal grandfather Lucius Scribonius Libo (the consul in AD 16) descended from his paternal grandmother Cornelia Sulla, a daughter of Pompeia and her first husband Faustus Cornelius Sulla. Therefore, his maternal grandmother Cornelia Pompeia was a daughter of Pompeia through her second marriage with Lucius Cornelius Cinna.
