RELATED:
- Yarrow
Origin:
Botanical name, EnglishMeaning:
"rough stream"Description:
Highly unusual as a baby name for either gender, Yarrow is an herb that grows wild and has long been used for its medicinal property. It's named for the mythical Achilles, who was said to carry yarrow into battle.
- Peregrine
Origin:
LatinMeaning:
"traveler, pilgrim"Description:
Peregrine is considered to be an elegantly aristocratic name in England, but has never made it to the U.S., where it has been seen as extravagantly eccentric. In the new naming climate, though, it's not beyond consideration — in fact it's already been chosen by at least one Berry.
- Florian
Origin:
LatinMeaning:
"flowering"Description:
If Flora and Florence have returned full force, Florian, with its trendy Latinate ending, could also have a chance. Popular in Germany, Austria, Switzerland, Poland, and France, St Florian was the venerated patron saint of those in danger from water and the patron saint of firefighters.
- Bartholomew
Origin:
AramaicMeaning:
"son of the furrow"Description:
Bartholomew is an apostle's name that's been out of favor for centuries but might appeal again to the parent in search of an old but rare choice. The challenge could be to avoid the Simpson-ish nickname. That character, by the way, has the full name of Bartholomew JoJo Simpson, and creator Matt Groening came up with Bart as an--uh oh--anagram for brat. Two old alternate nicknames are Barty and Tolly.
- Wilbur
Origin:
GermanMeaning:
"resolute, brilliant"Description:
Wilbur is a stylish name in the UK whose merits are just starting to be discovered in the US. Wilbur, the loveable pig who Charlotte of the Web called Some Pig, is an inspirational hero. And Wilbur and Orville Wright were early aviationists.
- Juniper
Origin:
English from Latin tree nameMeaning:
"young"Description:
Juniper is a nature name that we really like. While it's trendiest for girls -- about 2500 baby girls were named Juniper in 2022 versus 34 baby boys -- the most notable Juniper in history was the saint Brother Juniper, a follower of Saint Francis renowned for his generosity. Blessed Junipero Serra, who founded the first of the California Missions, took his name from the earlier Saint Juniper.
- Ivo
Origin:
GermanMeaning:
"yew wood, archer"Description:
Ivo is an unusual, catchy name with the energetic impact of all names ending in 'o'. Hardly heard in the U.S., it is used a bit more frequently in England, as is the related Ivor, a favorite of such novelists as Evelyn Waugh and P.G. Wodehouse. Ivo is currently most popular in the Netherlands.
- Cato
Origin:
LatinMeaning:
"all-knowing"Description:
Cato conjures up images of ancient Roman statesmen and southern antebellum retainers; it could have revival potential, with its 'O' ending and the current interest in the names of Greek and Roman antiquity.
- Bram
Origin:
Dutch variation of Abraham, HebrewMeaning:
"father of multitudes"Description:
Bram has an unusual measure of character and charm for a one-syllable name; it started as a hipper-than-Abe diminutive of the biblical Abraham, but is also an independent Irish and Dutch name, made famous by Irish-born Dracula creator Bram (nee Abraham) Stoker. Bram is currently Number 16 in the Netherlands; Bram Howard was a character on The West Wing.
- Isidore
Origin:
GreekMeaning:
"gift of Isis"Description:
Isabel and Isadora are back: could it now be time for a more widespread revival of Isidore? In 2014, both Isidore and Isadore were on the list of fastest-rising names in the US.
- Marlowe
Origin:
Variation of Marlow, EnglishMeaning:
"driftwood"Description:
While Marlowe (and Marlow and Marlo) are surname names that are not intrinsically or traditionally gendered and so in theory work equally well for boys and girls. About 10 percent of the babies named Marlowe are boys, while Marlow is 25 percent male and Marlo is about 50-50.
- Oberon
Origin:
Variation of AuberonMeaning:
"elf king; noble bear"Description:
The Shakespearean character Oberon in A Midsummer Night's Dream is King of the Fairies, but the name, with its bold 'O' beginning has plenty of strength alongside its magical qualities.
- Fraser
Origin:
Scottish from FrenchMeaning:
"strawberry"Description:
Though TV's "Frasier" made the name famous, and Frazier is a well-used variation, Fraser is the original, used mostly in Scotland.
- Cyril
Origin:
GreekMeaning:
"lordly"Description:
A British-accented Greek name with an intellectual image that has been off the U.S. charts since 1966, but was a Top 300 name at the turn of the last century. We have the feeling Cyril's ready for a comeback.
- Ilya
Origin:
Russian variation of ElijahMeaning:
"the Lord is my God"Description:
A rare example of an a-ending boy's name that sounds masculine, Ilya has a large measure of creative Slavic charm. >p>Ilya Ilyich Oblomov is the central character in Goncharov's novel "Oblomov." Unfortunately, he spends most of his life in his bathrobe and slippers.
- Oisin
Origin:
IrishMeaning:
"little deer"Description:
Oisin is one of the most popular Irish baby names in its native land, though largely unknown in the US. The original Oisin was the mythological son of Finn McCool and Sadb, the goddess who was changed into a deer. A legendary war hero and poet, Oisin had a name that is also reminiscent in sound of the ocean. Pronounced correctly, this name has an attractive sheen.
- Murray
Origin:
ScottishMeaning:
"settlement by the sea"Description:
Murray, you may be surprised to discover, is a Scottish surname name --that of an ancient noble clan--with a sea-swept meaning, and just could be in the next wave of reevaluated grandpa names. Currently Number 60 for baby boys born in its native Scotland; it was at its highest in the US in 1922, when it reached Number 208, but has been off the list since 1975. Could it be time for a comeback?
- Laszlo
Origin:
HungarianMeaning:
"glorious ruler"Description:
The Hungarian classic Laszlo, with its zippy 'z' middle and energetic 'o' ending, has become something of a hipster option, beginning to be considered by cutting-edge parents.
- Penn
Origin:
EnglishMeaning:
"enclosure"Description:
This simple, elegant name offers something for many kinds of parents, from writers and history buffs to photographers to Pennsylvania dwellers. Most famous bearers are comedian Penn Jillette and Gossip Girl hottie Penn Badgley, both of whom were given this distinctive name at birth. Long obscure, Penn seems destined for greater usage.
- Willow
Origin:
English tree nameMeaning:
"willow tree"Description:
Fresh and surprising on a boy – and how can you not love the cool classic nickname Will?
