Number Names for Babies

What is so rare as a month named June? October – and November and December – are a lot rarer. Brisk and substantial, they're so much more memorable and modern than April or May. October got its name via being the eighth month in the old Roman calendar.

The name of several popes and saints, Sixtus is certainly unusual but would have trouble making it in the modern world outside the Vatican. Even worse is its brother Sextus. Try making it through seventh grade with that name.

This unusual surname name has been made famous by Pretty Little Liars actress Troian Bellisario. Troian is a family name on her father's maternal side, possibly meaning "of Troy", but more likely deriving from a Slavic name meaning "triad; trinity".

While Sixtine is a name with ancient roots that's popular in modern-day France, it's hard to imagine it gaining hold in English-speaking lands, given its similarity to the number sixteen and its even-more-problematic similarity to the word "sexting." You wouldn't do that to your daughter.

A literary name figuring in the story of Ben Hur and the novels of Anthony Trollope that has the feel of Roman antiquity that is beginning to appeal to many parents. Quintus was one of only about twenty male first names in ancient Rome, and was often (though not exclusively) used for fifth sons.

Authentically spelled İlkin, this would be an unusual (to English speakers) pick for a firstborn boy.

Ensio derives from the Finnish word ensimmäinen, meaning "first one."

Traditional Swahili choice for the eldest child.

This Cornish word name would make an excellent choice for a first-born daughter.

In the days of huge families, this name of the Roman goddess of prophecy and childbirth, and one of the Fates, would be saved for bambina number ten. Now it might be used for a girl born in October, the tenth month.

The revival of long-dormant Roman names would put this back in the lexicon if it wasn't so connected to a telecommunications network.

It's difficult to conceptualize the numerical value of a trillion, but this extraordinarily large number name is a rising choice for baby boys.

More unusual than Tessa, this would make an interesting, meaningful and attractive choice for a third child.

Unlucky number thirteen is now an edgy baby name option thanks to Kourtney Kardashian and Travis Barker, who named their son Rocky Thirteen. They chose his one-of-a-kind middle name because "13 is just the greatest number of all time," according to Barker. Rocky is also the 13th Kardashian grandchild.

Now that Kenji is rising up the ranks, it's only a matter of time before parents discover Renji. Renji Abarai is a character in the anime series Bleach, in which the kanji used for his name mean "second love" or "second romance."

Name for a seventh child, back when people had them.

Seinfeld's George threatened to name his future child Seven, and then singer Erykah Badu actually did it.

If Erykah Badu can name her son Seven, why can't you name your daughter (or son) this? Eleven has recently gotten a lot of attention via the character on the TV show Stranger Things.

The name of an early Greek god of the sea, after whom a moon of Neptune is named.

Twain can be thought of as a modernization (and possible namesake) of the dated Wayne, seasoned with the humor of Mark Twain, who adopted it from a river term.
