By generation
In the Julio-Claudian dynasty of Roman emperors, the lineage of the Julii Caesares was separated from those of the Claudii up to Augustus' generation. The next generation had both Claudii with a Julia as ancestor, as Claudii adopted into the Julii Caesares family. After Tiberius, the remaining three emperors of the dynasty had, outside adoptions, ancestors in both the Julian and the Claudian families.
Antonia Major's generation
Octavianus, becoming Augustus the first Roman emperor, married Scribonia who gave him a daughter (Julia the Elder). His last marriage was with Livia, a Claudia who had been married to a Claudius. Their son Tiberius, by birth a Claudius, was later adopted by Augustus, thus, like his stepfather Augustus, becoming one of the Julii Caesares by adoption.

Agrippina the Elder's generation
Without son, Augustus had adopted his grandsons (by his only daughter Julia) Gaius, Lucius and Postumus, and his stepson Tiberius, in order to ensure an heir and successor. Around the time of his death only Tiberius remained and he became the next emperor. Tiberius, a Claudius by birth had become one of the Julii Caesares by adoption: from this moment this first dynasty of Roman emperors was both Julian and Claudian. The further emperors of this dynasty had both Julian and Claudian ancestors.

Agrippina the Younger's generation
Caligula was the last emperor adopted into the family of the Julii Caesares. He was a Claudius by descendance, although he had Julii Caesares among his ancestors, from both his mother's and his father's side.

Most marriages remained childless and many potential successors in the dynasty were eliminated after rampant accusations.
Claudius, the fourth emperor of the Julio-Claudian dynasty, was a brother to Caligula's father Germanicus. He belonged to the gens Claudia with, from his mother's side, Julian ancestors.

Poppaea Sabina's generation
Nero, the last emperor of the dynasty, was by birth a Domitius with as well Julian ancestors (from both his mother's as his father's side), as Claudian (from his mother's side). He became a Claudian himself, by adoption by his stepfather emperor Claudius, a brother to his grandfather from his mother's side, or, from his father's side, a son of his grandmother's sister.

(Vipsania) Agrippina the Elder was a prominent member of the Julio-Claudian dynasty. She was the daughter of Marcus Vipsanius Agrippa and Augustus' daughter, Julia the Elder. Her brothers Lucius and Gaius Caesar were the adoptive sons of Augustus, and were his heirs until their deaths in AD 2 and 4, respectively. Following their deaths, her second cousin Germanicus was made the adoptive son of Tiberius, Augustus' stepson, as part of the succession scheme in the adoptions of AD 4. As a result of the adoption, Agrippina was wed to Germanicus in order to bring him closer to the Julian family.
The Julio-Claudian dynasty comprised the first five Roman emperors: Augustus, Tiberius, Caligula, Claudius, and Nero.
Livia Drusilla was Roman empress from 27 BC to AD 14 as the wife of emperor Augustus. She was known as Julia Augusta after her formal adoption into the Julian family in AD 14.
Marcus Agrippa Postumus, later named Agrippa Julius Caesar, was a grandson of Roman Emperor Augustus. He was the youngest child of Marcus Vipsanius Agrippa and Julia the Elder. Augustus initially considered Postumus as a potential successor and formally adopted him as his heir, before banishing Postumus from Rome in AD 6 on account of his ferocia. In effect, though not in law, the action cancelled his adoption and virtually assured Tiberius' emplacement as Augustus' sole heir. Postumus was ultimately executed by his own guards shortly after Augustus' death in AD 14.
Gaius Caesar was the grandson and heir to the throne of Roman emperor Augustus, alongside his younger brother Lucius Caesar. Although he was born to Marcus Vipsanius Agrippa and Julia, Augustus' only daughter, Gaius and his younger brother, Lucius Caesar, were raised by their grandfather as his adopted sons and joint-heirs to the empire. He would experience an accelerated political career befitting a member of the Julio-Claudian dynasty, with the Roman Senate allowing him to advance his career without first holding a quaestorship or praetorship, offices that ordinary senators were required to hold as part of the cursus honorum.
The gens Claudia, sometimes written Clodia, was one of the most prominent patrician houses at ancient Rome. The gens traced its origin to the earliest days of the Roman Republic. The first of the Claudii to obtain the consulship was Appius Claudius Sabinus Regillensis, in 495 BC, and from that time its members frequently held the highest offices of the state, both under the Republic and in imperial times.
Julia is the nomen of various women of the family Julii Caesares, a branch of the gens Julia, one of the most ancient patrician houses at ancient Rome.
The gens Julia was one of the most prominent patrician families in ancient Rome. Members of the gens attained the highest dignities of the state in the earliest times of the Republic. The first of the family to obtain the consulship was Gaius Julius Iulus in 489 BC. The gens is perhaps best known, however, for Gaius Julius Caesar, the dictator and grand uncle of the emperor Augustus, through whom the name was passed to the so-called Julio-Claudian dynasty of the first century AD. The nomen Julius became very common in imperial times, as the descendants of persons enrolled as citizens under the early emperors began to make their mark in history.
Claudia Livia was the only daughter of Nero Claudius Drusus and Antonia Minor and sister to Roman Emperor Claudius and general Germanicus, and thus paternal aunt of emperor Caligula and maternal great-aunt of emperor Nero, as well as the niece and daughter-in-law of Tiberius. She was named after her grandmother, Augustus' wife Livia Drusilla, and commonly known by her family nickname Livilla. She was born after Germanicus and before Claudius.
Drusus Caesar was the adopted grandson and heir of the Roman emperor Tiberius, alongside his brother Nero. Born into the prominent Julio-Claudian dynasty, Drusus was the son of Tiberius' general and heir, Germanicus. After the deaths of his father and of Tiberius' son, Drusus the Younger, Drusus and his brother Nero Caesar were adopted together by Tiberius in September AD 23. As a result of being heirs of the emperor, he and his brother enjoyed accelerated political careers.
Rubellius Plautus was a Roman noble and a political rival of Emperor Nero. Through his mother Julia, he was a relative of the Julio-Claudian dynasty. He was the grandson of Drusus, and the great-grandson of Tiberius and his brother Drusus. Through his great-grandmothers Vipsania Agrippina and Antonia Minor, he was also descended from Marcus Vipsanius Agrippa and Mark Antony. He was descended from Augustus' sister Octavia Minor, herself a grand-niece of Julius Caesar.
Nero Julius Caesar was the adopted grandson and heir of the Roman Emperor Tiberius, alongside his brother Drusus. Born into the prominent Julio-Claudian dynasty, Nero was the son of Tiberius' general and heir, Germanicus. After the deaths of his father and of Tiberius' son, Drusus the Younger, Nero and his brother Drusus were adopted together by Tiberius in September AD 23. As a result of being heirs of the emperor, he and his brother enjoyed accelerated political careers.
Gnaeus Domitius Ahenobarbus was a member of the imperial Julio-Claudian dynasty of Ancient Rome. Domitius was the son of Antonia Major. He married Agrippina the Younger and became the father of the emperor Nero.
Lucius Caesar was a grandson of Augustus, the first Roman emperor. The son of Marcus Vipsanius Agrippa and Julia the Elder, Augustus' only daughter, Lucius was adopted by his grandfather along with his older brother, Gaius Caesar. As the emperor's adopted sons and joint-heirs to the Roman Empire, Lucius and Gaius had promising political and military careers. However, Lucius died of a sudden illness on 20 August 2 AD, in Massilia, Gaul, while traveling to meet the Roman army in Hispania. His brother Gaius also died at a relatively young age on 21 February 4 AD. The untimely loss of both heirs compelled Augustus to redraw the line of succession by adopting Lucius' younger brother, Agrippa Postumus as well as his stepson, Tiberius on 26 June 4 AD.
Vipsania Julia Agrippina nicknamed Julia Minor and called Julia the Younger by modern historians, was a Roman noblewoman of the Julio-Claudian dynasty. She was emperor Augustus' first granddaughter, being the first daughter and second child of Julia the Elder and her husband Marcus Vipsanius Agrippa. Along with her siblings, Julia was raised and educated by her maternal grandfather Augustus and her maternal step-grandmother Livia Drusilla. Just like her siblings, she played an important role in the dynastic plans of Augustus, but much like her mother, she was disgraced due to infidelity later on in her life.
Gaius Octavius was a Roman politician. He was an ancestor to the Roman emperors of the Julio-Claudian dynasty. He was the father of the emperor Augustus, step-grandfather of the emperor Tiberius, great-grandfather of the emperor Claudius, and great-great grandfather of the emperors Caligula and Nero. Hailing from Velitrae, he was a descendant of an old and wealthy equestrian branch of the plebeian gens Octavia. Not being of senatorial rank, he was a novus homo at Rome. His grandfather, Gaius Octavius, fought as a military tribune in Sicily during the Second Punic War. His father, Gaius Octavius, was a municipal magistrate who lived to an advanced age.
Marcus Livius Drusus Claudianus was a senator and praetor of the Roman Republic. He was born with the name Appius Claudius Pulcher, into the patrician family of the Claudii Pulchri but adopted by a Livii Drusi as a small child. His daughter Livia Drusilla became the wife of the first Roman Emperor Augustus, and he was a direct ancestor of the Julio-Claudian emperors Tiberius, Caligula, Claudius and Nero.
Octavia the Younger was the elder sister of the first Roman Emperor, Augustus, the half-sister of Octavia the Elder, and the fourth wife of Mark Antony. She was also the great-grandmother of the Emperor Caligula and Empress Agrippina the Younger, maternal grandmother of the Emperor Claudius, and paternal great-grandmother and maternal great-great-grandmother of the Emperor Nero.
The Julii Caesares were the most illustrious family of the patrician gens Julia. The family first appears in history during the Second Punic War, when Sextus Julius Caesar was praetor in Sicily. His son, Sextus Julius Caesar, obtained the consulship in 157 BC; but the most famous descendant of this stirps is Gaius Julius Caesar, a general who conquered Gaul and became the undisputed master of Rome following the Civil War. Having been granted dictatorial power by the Roman Senate and instituting a number of political and social reforms, he was assassinated in 44 BC. After overcoming several rivals, Caesar's adopted son and heir, Gaius Julius Caesar Octavianus, was proclaimed Augustus by the senate, inaugurating what became the Julio-Claudian line of Roman emperors.
