The Caecilii Metelli were an illustrious family of the Roman republic.
Lucius' grandfather was Quintus Caecilius Metellus Macedonicus.
[1] Lucius' father was Gaius Caecilius Metellus Caprarius, Macedonicus' youngest son.
Lucius' sister, Caecilia Metella, was married to Gaius Verres.
Lucius's family supported Verres, and were well-positioned to support him: Lucius was Governor of Sicily when the trial took place, his elder brother, Creticus, was to be consul in 69 BC along with fellow Verres supporter Quintus Hortensius Hortalus, and Marcus, the youngest brother, was to be president of the extortion court in 69 BC.
Because of this, Verres unsuccessfully tried to put off the trial until 69 BC, when the Caecilii Metelli and Hortensius would have the power to gain his acquittal.
