I was wondering when you'd notice.
Marcellus Mastrannus, you are descended from that ill-fated imposter, Amatius "who pretended to be either the son or grandson of the great Marius. On the death of Julius Caesar B.C. 44, he came forward as a popular leader, and erected an altar to Caesar on the spot where his body had been burnt. He was, however, shortly afterwards seized by the consul Antony and put to death without a trial."
Unlike your ancestor, you have refrained from any tendencies towards impersonation of the famous, and have subsequently fared better. Like your ancestor, you bear the gens name of Amatius. However, your cognomen is Habens, literally meaning "having; holding," and indicating that you possess property and are very wealthy. Your praenomen is "Spurius," abbreviated as "S." Your full Roman name is:
S. Amatius Habens
