Numerical baby names are monikers that parents can always count on. While all names hold a special meaning and significance, number names trace their origins to a number or numerical concept. These names can honor family by denoting the number of children. These baby names can also be signifiers for dates. Perhaps your baby boy was born in August or on the eighth of the month, then you could with Octavius, which means “eighth.”
If you are not trying to find anything specific to a number and, instead, are after attractive names for baby boys, you’ll also find them within this list. After all, many of these names have been around since the ancient Romans began using them as names centuries ago. That means that these names are versatile, well-known, and beloved classics. All-in-all, these names really add up! Check out these 25 numerical baby names for boys and get inspired by the numerals.
Ensio derives from the Finnish word ensimmäinen, meaning “first one.” Thus, Ensio means “first.” The name is pronounced EHN-see-oh which should not be too difficult for others to pick up thanks to more popular names like Enzo and Elio.
Primo is number one among the Latin birth-order names like Octavius. Primo stands out because it ends in the trendy O-sound that so many new parents are after. The name means “first” and definitely sounds superlative.
Basketball’s Jayson Tatum introduced this moniker to the naming lexicon when he used it as a clever nickname for his son, Jayson Christoper Jr. Deuce has English origins as a name meaning “two.” For your second son, consider this name as a given or middle option.
Twain is an archaic word for “two.” Twain works thanks to the popularity of Wayne, but it offers more fun and humor when associated with Mark Twain. This name has never appeared in the top 1000 names in the US, but we see that changing in the coming years.
After your first little Primo, you could always call the next Segundo! Segundo is a Spanish name that means “second-born.” This name is on the rise and while it’s off the radar of many new parents, the name has a storied history. Get on this train now before this name really takes off.
Tripp is a classic nickname for a third. Like Trace and Trey, it’s becoming a popular name in its own right for the children of juniors. The name made an impressive debut on the top 1000 in 2008 and its popularity continues to grow. If you’re looking for a casual and playful name, this would be a great option.
Quade is most widely accepted as an Irish surname that means “son of Uaid.” However, this is a subtle number name because it’s associated with the Latin word for “fourth.” However you slice it, this would make for a distinguished given name for a boy.
Quentin, a unique name with lots of character, relates to the Latin for the number five and is by far the craftiest and most usable of the Latin birth-order names. Quentin sounds masculine as well as stylish and distinctive. The name means “fifth.” The name has been falling in favor since the late 1990s and we’d love to see a change in its fortune.
The Japanese element, “-ro” means “son” and is a part of many Japanese names for boys. Jiro is one of the most popular, meaning “second son.” There’s also Ichiro (“first son”), Saburo (“third son”), Shiro (“fourth son”), etc.
Septimus, like Quentin, is a distinguished birth-order name with Latin origins. Septimus means “seventh son.” Roman Emperor Septimus Severus popularized this awesome name. He was a patron of the arts. While you might not plan on having seven children, this still makes for an exceedingly special name.
Otto is a name that’s popular in the US again after falling off the charts for years. We’re thrilled that this German name has made a comeback. The German meaning of this name is “wealthy.” Coincidentally, the name means “eight” in Italian.
Decio is the preferred Spanish and Italian form of the Latin name, Decimus. However, the name is pronounced differently in each language. It’s DEH-sio in Spanish and DEH-chio in Italian. However you say it, the name means “tenth.”
We’re dipping back into Japanese baby names for a moment because they’re oh, so nice. Kuro was a name traditionally given to the ninth born son of a family and thus it means “ninth son” or “black.”
Authentically spelled İlkin, this would be an unusual pick for a firstborn son for most English speakers. The name has Turkish and Azerbaijani origins and, you guessed it, means “first.” The name is pronounced EEL-keen and we’re very keen on it.
A traditional Swahili choice for an eldest son, Mosi is a precious name. Thus, the name means “number one.”
Proteus will certainly turn some heads! Proteus is a name of Greek origin and name to a mythic sea god. Proteus means “firstborn.” This is quite a weighty moniker and we would not blame you if you thought it was “too much.” Be bold, parents!
Troian is the only Slavic name to make this list, this is a surname, now used as a given name. It means “trinity.” Troian is pronounced TROY-an which includes the popular Troy element.
Erykah Badu and Andre 3000 caused a stir when they chose the name Seven for their son. This English word and number name works well as a gender-neutral option. It’s a name on the rise and we expect to see it fully seated in the top 1000 when 2020s baby-naming data is released.
We briefly covered Trey earlier in relation to Tripp, but we think it deserves its own spot on the list. Trey has been a steadily trending name since the sixties and it has a vintage charm to it. Not complicated and very casual, Trey feels like the perfect name for a “third son” that does not feel overly burdened.
Solo is a word name that’s taken off in recent years and we expect the name to be even more widely favored. It’s an excellent unisex name that means “one person alone.” This Italian gem sounds great as both a given and middle name.
Adamo is a name with Hebrew origins that means “son of the red earth” or “first son.” It’s one of the most popular and beloved names around the world and can be found in many forms, including the ubiquitous, Adam. If you’re looking for a traditional name with a romantic spin on it, consider Adamo.
With the stunning popularity of the Hawaiian name Kai in recent years, we thought it appropriate to bring you another Hawaiian option that’s equally as adorable. Hilo means “first night after the new moon.” The name also applies to the Polynesian navigator and a town in Hawaii.
Ace is a name for boys that is hotter now than ever before. The name has Latin origins and means “one” or “unity.” Once only used as a nickname, new parents have realized this name’s endearing charms over the last two decades.
Ulan is a Twi (spoken in Ghana) name that means “firstborn twin.” If you’re looking for a very unique name to honor your heritage, this would be the perfect choice for an older twin. The name is pronounced oo-lahn.
Leif is pronounced LAYF or LEEF is one of the most widely known, traditional Scandinavian names thanks to Icelandic explorer Leif Erikson. It’s commonly mispronounced as “leaf” in the US and other English-speaking countries. However you decide to pronounce it, this excellent name means “first heir” or “descendant.”
