Mary Beard surprises with this bit 0f information about the Roman Catiline's lineage in SPQR:
Among his blue-blooded forebears, his great-grandfather was a hero of the war against Hannibal, with the extra claim to fame of being the first man known to have entered combat with a prosthetic hand – probably just a metal hook that replaced his right hand, lost in an earlier battle.
