 However, adoption did not result in the complete abandonment of the adopted son's birth name.The son's original nomen (or occasionally cognomen) would become the basis of a new surname, formed by adding the derivative suffix "-anus" or "-inus" to the stem.Thus, when a son of Lucius Aemilius Paullus was adopted by Publius Cornelius Scipio, he became Publius Cornelius Scipio Aemilianus; in his will, the dictator Gaius Julius Caesar adopted his grandnephew, Gaius Octavius, who became known as Gaius Julius Caesar Octavianus.
