In the Roman empire, people were given three names: a praenomen (personal name), nomen (family name), and cognomen (originally a nickname, later used as another family name). For example, the politician Cicero's full name was Marcus Tullius Cicero (pronounced kee-ker-oh in Latin), with Cicero being a cognomen meaning "chickpea". Apparently, one of his ancestors had a cleft in his nose that looked like a chickpea, and the term stuck. Several other cognomens also had to do with legumes - Lentulus, Fabius, and Piso meant "lentil", "bean", and "pea" - and many more followed earthy or simple themes. The Caesar part of Julius Gaius Caesar may have meant something like "head of hair", "bluish-gray", or something else, depending on which historians you consult.
