Meaning:strong-willed warrior; with gilded helmet
Guillermo is a baby boy name of Mexican and Spanish origin meaning “strong-willed warrior” and “with gilded helmet”. The Spaniards of the early days are known as prolific conquerors, no doubt in thanks to the aforementioned strong-willed warriors. But if your little Guillermo is more of the gentle-natured sort, this name comes with a sweet diminutive and a celebration of baby’s heritage. Originally known as a Spanish language variant of William, this name could tie in baby’s Anglo-Saxon heritage, too. But regardless, little Guille could become a resolute protector of anything and anyone they love with such a rich background to lean on.
