Marcus Aurelius child Lucilla
Marcus Aurelius Antoninus (Latin: [ˈmaːr.kus̠ auˈreː.li.us̠ an.toː.ˈniː.nus̠]; English:  aw-REE-lee-əs; 26 April 121 – 17 March 180) was Roman emperor from 161 to 180 AD and a Stoic philosopher. He was the last of the rulers known, noncontemporaneously, as the Five Good Emperors and the last emperor of the Pax Romana, an age of relative peace, calmness and stability for the Roman Empire lasting from 27 BC to 180 AD. He served as Roman consul in 140, 145, and 161. 
Marcus Aurelius was born during the reign of Hadrian to the emperor's nephew, the praetor Marcus Annius Verus, and the heiress Domitia Calvilla. His father died when he was three, and he was raised by his mother and paternal grandfather. After Hadrian's adoptive son, Aelius Caesar, died in 138, the emperor adopted Marcus's uncle Antoninus Pius as his new heir. In turn, Antoninus adopted Marcus and Lucius, the son of Aelius. Hadrian died that year, and Antoninus became emperor. Now heir to the throne, Marcus studied Greek and Latin under tutors such as Herodes Atticus and Marcus Cornelius Fronto. He married Antoninus' daughter Faustina in 145.
After Antoninus died in 161, Marcus Aurelius acceded to the throne alongside his adoptive brother, who reigned under the name Lucius Verus. Under his rule the Roman Empire witnessed heavy military conflict. In the East, the Romans fought successfully with a revitalized Parthian Empire and the rebel Kingdom of Armenia. Marcus defeated the Marcomanni, Quadi, and Sarmatian Iazyges in the Marcomannic Wars; however, these and other Germanic peoples began to represent a troubling reality for the Empire. He modified the silver purity of the Roman currency, the denarius. The persecution of Christians in the Roman Empire appears to have increased during his reign, but his involvement in this is unlikely since there is no record of early Christians in the 2nd century calling him a persecutor, and Tertullian even called Marcus a "protector of Christians". The Antonine Plague broke out in 165 or 166 and devastated the population of the Roman Empire, causing the deaths of five to ten million people. Lucius Verus may have died from the plague in 169.
Unlike some of his predecessors, Marcus chose not to adopt an heir. His children included Lucilla, who married Lucius, and Commodus, whose succession after Marcus has been a subject of debate among both contemporary and modern historians. The Column and Equestrian Statue of Marcus Aurelius still stand in Rome, where they were erected in celebration of his military victories. Meditations, the writings of "the philosopher" – as contemporary biographers called Marcus – are a significant source of the modern understanding of ancient Stoic philosophy. These writings have been praised by fellow writers, philosophers, monarchs, and politicians centuries after his death.Family origins
Marcus' paternal family was of Roman Italo-Hispanic origins. His father was Marcus Annius Verus (III). The gens Annia was of Italic origins (with legendary claims of descendance from Numa Pompilius) and a branch of it, the Annii Veri, moved to Ucubi, a small town south east of Córdoba in Iberian Baetica. This branch rose to prominence in Rome in the late 1st century AD. Marcus's great-grandfather Marcus Annius Verus (I) was a senator and (according to the Historia Augusta) ex-praetor; his grandfather Marcus Annius Verus (II) was made patrician in 73–74. Through his grandmother Rupilia Faustina, Marcus was a member of the Nerva-Antonine dynasty; the emperor Trajan's sororal niece Salonia Matidia was the step-mother of Rupilia and her step-sister, Hadrian's wife Sabina.Marcus's mother, Domitia Lucilla Minor (also known as Domitia Calvilla), was the daughter of the Roman patrician P. Calvisius Tullus and inherited a great fortune (described at length in one of Pliny's letters) from her parents and grandparents. Her inheritance included large brickworks on the outskirts of Rome – a profitable enterprise in an era when the city was experiencing a construction boom – and the Horti Domitia Calvillae (or Lucillae), a villa on the Caelian hill of Rome. Marcus himself was born and raised in the Horti and referred to the Caelian hill as 'My Caelian'.The adoptive family of Marcus was of Roman Italo-Gallic origins: the gens Aurelia, into which Marcus was adopted at the age of 17, was a Sabine gens; Antoninus Pius, his adoptive father, came from the Aurelii Fulvi, a branch of the Aurelii based in Roman Gaul.Childhood
Marcus's sister, Annia Cornificia Faustina, was probably born in 122 or 123. His father probably died in 124, when Marcus was three years old during his praetorship. Though he can hardly have known his father, Marcus wrote in his Meditations that he had learned 'modesty and manliness' from his memories of his father and the man's posthumous reputation. His mother Lucilla did not remarry and, following prevailing aristocratic customs, probably did not spend much time with her son. Instead, Marcus was in the care of 'nurses', and was raised after his father's death by his grandfather Marcus Annius Verus (II), who had always retained the legal authority of patria potestas over his son and grandson. Technically this was not an adoption, the creation of a new and different patria potestas. Lucius Catilius Severus, described as Marcus's maternal great-grandfather, also participated in his upbringing; he was probably the elder Domitia Lucilla's stepfather. Marcus was raised in his parents' home on the Caelian Hill, an upscale area with few public buildings but many aristocratic villas. Marcus's grandfather owned a palace beside the Lateran, where he would spend much of his childhood. Marcus thanks his grandfather for teaching him 'good character and avoidance of bad temper'. He was less fond of the mistress his grandfather took and lived with after the death of his wife Rupilia. Marcus was grateful that he did not have to live with her longer than he did.– Iliad vi.146
Another daughter was born on 7 March 150, Annia Aurelia Galeria Lucilla. At some time between 155 and 161, probably soon after 155, Marcus's mother Domitia Lucilla died. Faustina probably had another daughter in 151, but the child, Annia Galeria Aurelia Faustina, might not have been born until 153. Another son, Tiberius Aelius Antoninus, was born in 152. A coin issue celebrates fecunditati Augustae, 'to Augusta's fertility', depicting two girls and an infant. The boy did not survive long, as evidenced by coins from 156, only depicting the two girls. He might have died in 152, the same year as Marcus's sister Cornificia. By 28 March 158, when Marcus replied, another of his children was dead. Marcus thanked the temple synod, 'even though this turned out otherwise'. The child's name is unknown. In 159 and 160, Faustina gave birth to daughters: Fadilla and Cornificia, named respectively after Faustina's and Marcus's dead sisters.
