Charo is of Spanish origin, meaning 'happy' or 'joyful'. It's a diminutive form of the name Carlos, which itself is derived from the Germanic word 'Karl', signifying 'freeholder' or 'strong'. Charo gained prominence in the late 20th century through its association with Charo Santos-Concio, a prominent Filipino actress and television personality. Despite being traditionally male due to its origins, Charo has also been used as a female name in some cultures.
"Charo experienced significant popularity among newborns from 1969 onwards, peaking in 1976 with 44 births. However, its usage declined sharply thereafter, reaching a low of 9 births in 1981."
