Question: Gaius Antonius Hybrida was the uncle of a politician born in which year ?
Context: The Lex Antonia de Termessibus was a Roman law passed in 71 or 68 BC, at the initiative of the tribune Gaius Antonius. Marcus Antonius (Latin: ; January 14, 83 BC – August 1, 30 BC), commonly known in English as Mark or Marc Antony, was a Roman politician and general who played a critical role in the transformation of the Roman Republic from an oligarchy into the autocratic Roman Empire. The Battle of Pistoria was fought in January of 62 BC between the forces of the Roman Republic and Catiline, a senatorial conspirator who wished to overthrow the republic, but failed in his objective.  Catiline had been denounced by Cicero, and was attempting to flee with his force into Gaul and had been blocked by forces of Quintus Metellus Celer and Gaius Antonius Hybrida (joint Consul with Cicero for the year in question).  Knowing that both armies were closing in on him, he decided to make a stand against Antonius Hybrida near Pistoria with his back against the mountains; he hoped that if he defeated Antonius, the other armies would lose morale and more people would flock to his cause.  Some sources say that Catiline might have faced Antonius hoping he might still switch sides.  Some accounts say Catiline had just over 10,000 men, which was about 2 legions worth, but it is not certain how many soldiers Gaius Antonius had under his command but Sallust states in his writings "The conspiracy of Catiline" that he outnumbered Catiline's forces .  On the day, Gaius Antonius Hybrida was said to have been struck by gout and command was passed to his lieutenant (Master of Horse) Marcus Petreius. Gaius Antonius (died 42 BC) was the second son of Marcus Antonius Creticus and Julia Antonia, and thus, younger brother of Mark Antony, who was one of the members of the second triumvirate. Gaius Plinius Caecilius Secundus, born Gaius Caecilius or Gaius Caecilius Cilo (61 – c. 113), better known as Pliny the Younger ( ), was a lawyer, author, and magistrate of Ancient Rome.  Pliny's uncle, Pliny the Elder, helped raise and educate him.  Both Pliny the Elder and the Younger were witnesses to the eruption of Vesuvius in 79 AD, in which the former died. Gaius Antonius Hybrida (flourished 1st century BC) was a politician of the Roman Republic.  He was the second son of Marcus Antonius and brother of Marcus Antonius Creticus; his mother is unknown.  He was also the uncle of the famed triumvir Mark Antony.  He had two children, Antonia Hybrida Major and Antonia Hybrida Minor. Lucius Julius Caesar (fl.  1st century BC) was a Roman politician and senator who was elected consul of the Roman Republic in 64 BC.  A supporter of his cousin, the Roman dictator Gaius Julius Caesar, Lucius was a key member of the senatorial faction which strove to avoid civil war between the Roman Senate and Marcus Antonius (Mark Antony) in the aftermath of the Dictator's assassination. The second Catilinarian conspiracy, also known simply as the Catiline conspiracy, was a plot, devised by the Roman senator Catiline, with the help of a group of fellow aristocrats and disaffected veterans of Lucius Cornelius Sulla, to overthrow the consulship of Marcus Tullius Cicero and Gaius Antonius Hybrida.  In 63 BC, Cicero exposed the plot, forcing Catiline to flee from Rome.  The conspiracy was chronicled by Sallust in his work The Conspiracy of Catiline, and this work remains an authority on the matter. Marcus Antonius Creticus (flourished 1st century BC) was a Roman politician, member of the Antonius family.  Creticus was son of Marcus Antonius and, by his marriage to Julia Antonia, he had three sons: Triumvir Marcus Antonius, Gaius Antonius and Lucius Antonius. The Battle of Histria, c. 62–61 B.C., was fought between the Bastarnae peoples of Scythia Minor and the Roman Consul (63 B.C.) Gaius Antonius Hybrida.  The Bastarnae emerged victorious in the battle after having successfully committed a surprise attack against Hybrida and his troops; Hybrida escaped alongside his cavalry forces leaving behind the infantry to be massacred by the Bastarnian-Scythian attackers.
