Gero is a name of German origin, derived from the Germanic elements 'ger' meaning 'spear' and 'mann', translating to 'spear strong'. It was popular among the Germans during the Middle Ages but has since declined in usage. The name Gero is associated with several notable figures throughout history, including Geronimo, a famous Apache leader. However, it remains relatively uncommon today.
"Gero was a popular baby boy name in 1970 with exactly five newborns sharing this unique moniker."
