Caro
Primarily a girl's name of Germanic origin with 269 recorded births. Also given to 5 boys.
Meaning & Origin
A diminutive of the female given name Caroline.
Caro is a girl's and boy's baby name of Germanic origin, a short form of Caroline or Carol, from the Old High German Karl, meaning 'free man.' Caro has been used as a nickname in England and France since the eighteenth century — the poet Lord Byron addressed many of his letters to 'Dear Caro' (Lady Caroline Lamb).
Caro has the breezy, Continental ease of Francophone nicknames-as-given-names — spare, charming, and effortlessly sophisticated.
EtymologyShow more
Caro first shows up in U.S. Social Security records in 1883. Names present in the earliest SSA data (which begins in 1880) were typically carried by immigrants from Europe, handed down through families, or drawn from biblical and classical sources.
Its Germanic classification suggests a path from germanic linguistic traditions into American usage, though the specific route — whether through immigration, literature, or cultural exchange — would require deeper historical research.
