The letter O can be very mighty; this strong, long vowel is a great way to give names a sense of power and presence. Spaniards have noticed this as well, and they’ve got plenty of boy names that start with this letter to prove it. Like many other given names from this country, many of our picks here are derived from Catholicism, as the religion has dominated the country for centuries.
Let’s kick off with Octavio; this robust name has a pretty simple meaning, merely denoting the eighth-born child in an obviously large family. We guess it makes sense to give children names depending on the order they were born in–especially in a Catholic country!
There’s also Oswaldo, which is pretty popular in Spain today. This name is clearly Christian-influenced, as it means “God’s rule.” While it’s a hit on the Iberian Peninsula, though, it’s neared the bottom of the U.S. Top 1000 Baby Names List for at least three years now.
Another Biblical name you’ll find here is Obed, which is a nod to the son of Old Testament believers Ruth and Boaz. The name comes from Hebrew originally, and means “serving and worshipping.”
That’s not all, though; we also love Oliviero, which is essentially the male counterpart to Olivia, and has the same meaning of “olive tree” as well. For a name that’s a bit closer to home, try Orlando. It means ‘famous land,’ which actually makes it quite fitting for the home of the happiest place on Earth: Disney World.
