Sergio
Meaning
from Roman family name Sergius, meaning uncertain
The story
Sergio descends from Sergius, one of Rome's oldest family names, so ancient that even the Romans were unsure what it meant. It was carried by four popes and an early saint, then lived on in Italian and Spanish as Sergio. The Spanish line produced one of soccer's most decorated defenders: Sergio Ramos, the Real Madrid great whose stoppage-time header in the 2014 Champions League final rescued the most famous of his many trophies, and who lifted the World Cup with Spain in 2010. In American records Sergio kept a quiet presence through the early twentieth century, then grew alongside the country's Spanish-speaking communities, with its strongest decades coming from the 1970s onward. It carries an old Roman gravity in three easy syllables, proof that a name can outlive its own meaning and be the better for it.
