3. M. AEMILIUS (REGILLUS), a brother of No. 2, whom he accompanied in the war against Antiochus : he died at Samos in the course of the year, B. C. 190. (Liv. 37.22.)

It would appear that this family became extinct soon afterwards. We learn from a letter of Cicero (Cic. Att. 12.24.2) that Lepidus, probably M. Aemilius Lepidus, consul B. C. 78, had a son named Regillus, who was dead at the time that Cicero wrote. It is probable that Lepidus wished to revive the cognomen of Regillus in the Aemilia gens, just as he did that of Paulus, which he gave as a surname to his eldest son. [See Vol. II. p. 765b.]
