Who was Quintus Fabius Maximus Aemilianus, Scipio Africanus the Younger's brother?

Quintus Fabius Maximus Aemilianus was the eldest son of the Roman general Lucius Aemilius Paullus Macedonicus and the elder brother of Scipio Africanus the Younger.1

As part of a common Roman practice to preserve noble families on the verge of extinction, he was adopted by a descendant of Quintus Fabius Maximus Cunctator, the celebrated general of the Second Punic War. Despite his adoption, he maintained a close relationship with his natural father and his brother, Scipio. In 168 BCE, he served alongside his father and brother during the Third Macedonian War, and he later benefited from the guidance of the Greek historian Polybius, who acted as a mentor to both brothers during their time in Rome.12
