- Morgan
Origin:
WelshMeaning:
"sea-born, sea-song or sea-circle"Description:
Morgan, once split evenly between the sexes, is a strong and attractive Welsh favorite, still a common boys’ name in Wales. Morgan is now more often a girls' name in the U.S. – about 2000 girls were given the name in one recent year, vs. 362 boys – though it's one of the most traditional unisex choices. Morgan was actually a Top 200 pick for boys in Victorian Britain!
- Maddox
Origin:
WelshMeaning:
"son of Madoc"Description:
Maddox, a previously obscure Welsh family name with a powerfully masculine image, suddenly came into the spotlight when Angelina Jolie chose it for her son in 2003. By the following year it was in the middle of the Top 1000, and it has risen since.
- Meredith
Origin:
WelshMeaning:
"great ruler"Description:
Meredith is a soft, gentle-sounding name with subtle Welsh roots. Although originally a boys’ name , Meredith is used mainly for girls now.
- Morgan
Origin:
WelshMeaning:
"sea-born, sea-song or sea-circle"Description:
Morgan has long been a traditional Welsh male name, a variant of the Old Welsh name Morcant, from the Welsh elements mor, meaning "sea" and cant, "circle." The female Morgan is unrelated to the male version—it is a name from Arthurian legend created for Morgan le Fay, King Arthur's half-sister and famed sorceress. Her name comes from Morgen, an Old Welsh name meaning "sea-born," and is related to the Irish name Muirgen.
- Megan
Origin:
Welsh diminutive of MargaretMeaning:
"pearl"Description:
Megan originally evolved from Meg, which itself derived as a nickname for Margaret. Margaret ultimately comes from the Greek word margarites, meaning "pearl." Megan is no longer a common nickname for Margaret—it is most often used as a full name. Other spellings include Meghan, Meagan, Megyn, and Meaghan.
- Macsen
Origin:
Welsh variation of Maximus, LatinMeaning:
"greatest"Description:
Macsen may sound like a modern invention, cousin to Jackson and Maxon, but it's a longtime Welsh variation of Maximus with evocative roots in legend. Macsen Wledig is another name for the Roman emperor Magnus Maximus, was played an important role in Welsh history and was further immortalized in a poem celebrating his dream about his lover Elen. Macsen also appears in Arthurian legend.
- Mari
Origin:
Welsh, Breton, Scandinavian, Hungarian, Estonian, and Basque variation of Maria or MaryMeaning:
"drop of the sea, bitter, or beloved"Description:
Mari enjoyed some mid-century popularity as a nicknameish version of Mary, but now deserves a second look as a multicultural classic. Mari is the name of the Basque goddess of fertility and weather and is also, for unrelated reasons, popular in Norway. The biggest problem with the potentially-lovely Mari will be getting people to say it the way you want. While some Europeans pronounce it as Marie, that will only confuse things more. Better to make it its own individual name by pronouncing it MAH-ree. As one commenter pointed out, in Estonian the name is not a Mary variation but means "berry" – all the more reason for us to like it!
- Meredith
Origin:
WelshMeaning:
"great chief"Description:
Meredith has been considered primarily a girl's name since the fifties, before which it was more commonly used for boys. Comic actor Jay Mohr recently named his son Meredith, which might help it swing back into the blue column. The traditional Welsh pronunciation puts the stress on the middle syllable, making Red a cool nickname possibility.
- Marvin
Origin:
Welsh, variant of MervynMeaning:
"sea hill"Description:
Marvin has been neglected for so long that it's hard to believe that it has windswept Welsh roots. It also has some strong namesakes going for it -- singer Marvin Gaye, composer Marvin Hamlisch and boxer Marvin Hagler. It's the real name of both Neil Simon and Meatloaf. And let's not forget mention Marvin Gardens on Monopoly.
- Merlin
Origin:
WelshMeaning:
"sea fortress"Description:
This name of the famous fifth-century sorcerer and mentor of King Arthur may or may not be a bit wizardy for a real-life modern child. Its most noted modern bearer: football star turned actor Merlin Olsen, whose father was named Merle.
- Morwenna
Origin:
WelshMeaning:
"maiden"Description:
Morwenna is an ancient Cornish name now being revived in Wales, deriving from a Celtic word meaning "maiden", although the Mor- syllable means that it's often associated with the sea. It's been heard in the British series Doc Martin and Poldark. Morwenna Banks is a British actress.
- Maxen
Origin:
Welsh, from Latin MaximusDescription:
Also spelled Macsen, this ancient name manages to sound modern and cool. An heroic namesake was Maxen Wledig, a fourth century Spanish-born general who led the Roman army out of Britain, and as Emperor was the most powerful occupant of the throne of the Caesars who had ever ruled Europe from the City of the Seven Hills.
- Mali
Origin:
Welsh form of Molly or ThaiMeaning:
"jasmine flower"Description:
Seems unfamiliar, till you realize everyone will just hear it as Molly. In Wales, Mali is a Top 100 name.
- Madoc
Origin:
WelshMeaning:
"fortunate, benefactor's son"Description:
Also spelled Madog, which was the name of an early Welshman, Madog ap Owain Gwynedd, reputed to have been the first European to discover North America in 1155. Maddox, the name of Angelina Jolie and Brad Pitt's oldest child, is a stronger and more familiar choice.
- Myfanwy
Origin:
WelshMeaning:
"my fine one, my woman"Description:
Intriguing Old Welsh name being revived there, but would have major pronunciation problems here.
- Meurig
Origin:
Welsh, from LatinMeaning:
"dark-skinned"Description:
The Welsh form of Maurice.
- Mair
Origin:
Welsh form of MaryDescription:
One of the many international versions of Mary that could make an unusual alternative. The similar sound to Maya/Maia could be a plus or a minus.
- Mervyn
Origin:
WelshMeaning:
"sea hill"Description:
Terminally outmoded.
- Morys
Description:
Morys is a masculine name of Welsh origin, representing a traditional Welsh form of 'Maurice.' The name ultimately derives from the Latin 'Mauritius,' meaning 'dark-skinned' or 'Moorish,' referring to the people of North Africa. While relatively uncommon in contemporary usage, Morys has deep historical roots in Welsh-speaking communities. It shares linguistic connections with Morris and Morrison. The name carries a dignified, somewhat antiquated character that connects to Welsh heritage and medieval European traditions. Morys might appeal to parents seeking a distinctive name with Celtic origins and historical significance, though its traditional nature and uncommon spelling may require occasional clarification in non-Welsh contexts.
- Mawrth
Description:
Mawrth is a masculine name with Welsh origins, representing the Welsh word for the planet Mars and also for Tuesday (the day of Mars). The name derives from the Roman god of war, Mars, adapted through Celtic language evolution. Extremely rare as a given name, Mawrth has significance in astronomy and Welsh cultural contexts. Interestingly, 'Mawrth Vallis' is a valley on Mars that has been studied for potential signs of past water. The name offers a distinctive option for parents with Welsh heritage or interests in Celtic languages, astronomy, or mythology, though its unusual pronunciation (similar to 'month' but with an 'r') might present challenges outside Wales.
