10 Girl Names Starting with Mo: Meanings, Origins & Popularity Rankings
1. Molly
Meaning and Cultural Origin
The name Molly traces its roots back to medieval England, where it began as a diminutive of Mary. It evolved from earlier forms like "Mally", with the substitution of "l" for "r", and also stems from the medieval names Malle and Molle. By 1720, Molly had become an independent name and was also used as a nickname for Margaret and Martha. Its origins span across Hebrew, Latin, and Celtic traditions, carrying meanings such as "star of the sea" and "wished-for child".
Modern or Classic Appeal
Molly strikes a balance between timelessness and contemporary charm. Though its usage dates back to the Middle Ages, the name saw a major revival in the late 20th century, consistently ranking as a top 100 name for American girls between 1987 and 2012. Figures like Molly Pitcher and Margaret Brown have added to its enduring appeal, making it both nostalgic and fresh. According to onomastician Cleveland Kent Evans, "Molly peaked with millennials", yet it remains relevant today, thanks in part to its ties to Cottagecore aesthetics and vintage-inspired trends.
Popularity and Uniqueness
Molly holds the distinction of being the most popular "Mo-" name for girls. In 2018, it ranked #158 in the U.S., with a usage rate of 0.097%. Impressively, it has stayed in the U.S. Top 500 since 1880. By 2024, it was ranked #208 in the United States. Globally, Molly has enjoyed consistent popularity, ranking among the top 100 names in countries like Australia, Ireland, New Zealand, Sweden, and the United Kingdom since the 1990s. Recent rankings include #22 in Ireland, #36 in Sweden, and #46 in Denmark for 2024/2025. This enduring presence highlights its universal appeal and paves the way for exploring other "Mo-" names.
2. Monica
Meaning and Cultural Origin
Monica is a name with a rich and layered history. It is believed to have originated in North Africa, with ties to Berber or Punic languages. The name is often associated with the Latin word monere, which means "to advise" or "advisor". Another interpretation links it to the Greek word monos, which translates to "alone", "unique", or "solitary".
One of the earliest known figures to bear this name was Saint Monica (322–387 AD), the devoted mother of Saint Augustine. She was born in Numidia, an area that is now part of modern-day Algeria. This connection gives the name a strong religious significance, particularly within Catholic communities. Over the centuries, Monica has crossed cultural boundaries, giving rise to variations like Monique in French, Monika in German and Scandinavian languages, and Mónica in Spanish and Portuguese-speaking regions. This blend of historical depth and cross-cultural appeal makes Monica a name that feels both timeless and versatile.
Modern or Classic Appeal
Monica is often seen as a classic name, thanks to its ancient roots and connection to Saint Monica. At the same time, it remains familiar and relevant in modern times, partly due to pop culture influences like Monica Geller from the hit TV show Friends. The character's traits - practicality, intelligence, and compassion - have added a contemporary layer to the name's personality.
The name had its peak moment in the United States in 1977, when it was ranked as the 39th most popular name for baby girls. Although its popularity has waned over the decades - dropping to 76th place in 1990 and 363rd by 2010 - this decline has given Monica a fresh appeal for parents. It’s a name that’s familiar yet not overly common, striking a balance between tradition and individuality.
Popularity and Uniqueness
As of 2024, Monica holds the #726 spot in U.S. baby name rankings. What sets Monica apart from other "Mo" names is its focus on wisdom and individuality. While names like Molly and Moira are tied to meanings like "star of the sea", and Morgan often relates to being "sea-born", Monica stands out with its emphasis on themes of guidance and uniqueness. This distinct meaning adds to its charm, making it a thoughtful choice for parents looking for a name with depth and character.
3. Morgan
Meaning and Cultural Origin
Morgan is a name with deep roots in Welsh and Irish traditions. Its Welsh origin stems from the Old Welsh name Morcant, which combines mor (meaning "sea") and cant (meaning "circle"). The Irish connection comes from Muirgen, which translates to "born of the sea". Together, these origins give Morgan its evocative meaning: "sea-born".
The name’s journey through time has expanded its identity. While traditionally a masculine name in Wales, Morgan has evolved into a widely embraced gender-neutral option, particularly in the United States. Adding to its allure is its connection to Arthurian legend - Morgan le Fay, the enchantress from King Arthur's tales, lends the name a touch of mysticism and intrigue.
Modern or Classic Appeal
Morgan strikes a balance between ancient heritage and contemporary style. Its Celtic roots provide a timeless foundation, while its rise as a popular name for girls in the U.S. reflects its modern adaptability. For instance, Morgan made its debut in the top 1,000 names for girls in 1976 at rank 913 and soared to 95th place by 1987.
"Morgan is currently more popular for girls than it is for boys in the US. But with its Welsh roots and Celtic charm, the name Morgan is a versatile and gender neutral name." - Shannon Day
The name’s popularity surge in the 1980s is often linked to actress Morgan Fairchild. This blend of ancient charm and modern flair has helped Morgan maintain its appeal across generations.
Popularity and Uniqueness
Morgan's peak as a girls' name came in 1997, when it ranked as the 22nd most popular name in the United States. However, its prominence has gradually waned, falling out of the top 100 by 2014.
Today, Morgan remains a familiar yet not overly common choice, celebrated for its gender-neutral versatility and strong ties to the sea. Currently ranked #276 for girls and #530 for boys, Morgan continues to offer a unique blend of tradition and modern appeal, firmly anchored in its maritime origins.
4. Moira
Meaning and Cultural Origin
Moira carries a rich dual heritage. It’s an Anglicized version of the Irish name Máire (Mary), which translates to "beloved", "drop of the sea", or "wished-for child." At the same time, it has roots in Greek mythology, derived from Μοῖρα, meaning "fate" or "destiny." In Greek lore, the Moirai were the three goddesses who controlled human destiny, giving the name a mystical and powerful undertone.
This name has been in use in English-speaking countries since the 19th century, gaining particular popularity in Scotland. Its layered background bridges timeless tradition with a modern-day charm.
Modern or Classic Appeal
Thanks to its deep origins, Moira is a name that feels both timeless and current. While its Irish and Scottish roots ground it in tradition, it’s still relatively uncommon in the United States, making it feel fresh. Pop culture has also played a role in its resurgence - think Moira Rose from Schitt’s Creek (2015), who helped elevate the name’s sophistication and trendiness.
"Well-established Irish and Scottish name that has never really caught on across the pond."
- Clare Green, Editor, Nameberry
Parents often associate Moira with qualities like elegance, maturity, and refinement, giving it an upper-class, polished feel.
Popularity and Uniqueness
Moira remains a rare gem in the United States. Its highest ranking was in 1965, when it reached #833. As of late 2025, it sits at #994 nationally. However, its popularity is higher among name enthusiasts, ranking #627 on Nameberry. Interest in the name surged by 22% in 2025, with a striking 28% increase during the last week of December [25,27].
Its rarity, combined with cultural depth, makes Moira stand out. Plus, its association with memorable fictional characters like Moira O'Deorain (Overwatch) and Moira MacTaggert (X-Men) adds to its blend of classic roots and modern relevance.
5. Mona
Meaning and Cultural Origin
The name Mona carries a rich tapestry of meanings from various cultures. In Irish and Gaelic traditions, it signifies "noble" or "aristocratic", sometimes interpreted as "little noble one". In Spanish, as a diminutive of Ramona, it translates to "protecting hands". From an Arabic perspective, Mona conveys the heartfelt notion of a "wish" or "desire". Beyond these cultural roots, the name is famously associated with Leonardo da Vinci’s iconic painting, the Mona Lisa, adding an artistic and refined dimension to its legacy. This blend of meanings and cultural influences makes Mona a name that feels both rooted in history and distinctively individual.
Modern or Classic Appeal
Mona strikes a perfect balance between classic elegance and modern simplicity. Its two-syllable structure makes it easy to say and remember, while its historical depth lends it a timeless charm. Though its popularity peaked between the 1950s and 1970s, Mona continues to hold its own, offering a sophisticated choice that never feels outdated. With just four letters, it’s a concise yet meaningful option that appeals to those seeking a name with enduring appeal.
Popularity and Uniqueness
Mona’s charm lies in its ability to balance familiarity with a touch of rarity. In the United States, it ranks as the 5th most popular girl name starting with "Mo", while in the United Kingdom, it holds the 4th spot. Though it follows names like Morgan, Molly, and Monica, it stands ahead of others such as Moriah, Montana, and Moana. What sets Mona apart is its self-contained simplicity. Unlike many "Mo" names that derive from nicknames (like Molly) or stretch into three syllables (like Monica or Montana), Mona is a complete, standalone name. This makes it a classic yet distinctive choice for parents drawn to its multicultural roots and understated elegance.
6. Maeve
Meaning and Cultural Origin
Maeve is a classic Irish name with rich layers of meaning, often translated as "the intoxicating one", "she who rules", or "mead-woman". Its roots trace back to the Old Irish name Medb (also spelled Meadhbh or Méabh), derived from the Proto-Celtic word medu- meaning "mead" - an ancient honey-based drink. Maeve holds a prominent place in Irish mythology, most famously represented by Queen Medb of Connacht. As a central figure in the Ulster Cycle and the epic Táin Bó Cúailnge, Queen Medb symbolizes power and sovereignty. In ancient Ireland, the act of a king receiving mead from a woman symbolized his right to rule, linking Maeve to themes of strength and enchantment that continue to resonate today.
Modern or Classic Appeal
Maeve seamlessly blends its ancient roots with a modern edge. Though steeped in Irish history, its short and sharp sound feels contemporary and stylish. The name aligns with today’s preference for simple, elegant names, and its "May" syllable conjures images of springtime and renewal. Unlike some other Irish names, such as Siobhan or Aisling, Maeve is easy for English speakers to pronounce, adding to its accessibility. Its popularity has also been boosted by appearances in pop culture, featuring in hit shows like The Boys, Westworld, and Sarah J. Maas’s Throne of Glass series.
Popularity and Uniqueness
Maeve's popularity has grown steadily in the United States over the years. It first broke into the top 1,000 names in 1997 at No. 955, climbed into the top 500 by 2013, and reached the top 300 in 2019. By 2024, it is projected to rank at No. 75. This consistent rise reflects its increasing appeal among American parents. Maeve strikes a perfect balance between being recognizable yet not overly common. While its roots are firmly Irish, its charm extends globally, with the highest search interest coming from Ireland, followed by Australia, the United Kingdom, and New Zealand. For parents seeking a name with mythological depth that pairs well with sibling names like Finn, Ronan, or Keira, Maeve offers a rare mix of strength, elegance, and accessibility. This enduring blend of history and modernity ensures Maeve’s place as a timeless choice.

7. Modesty
Meaning and Cultural Origin
The name Modesty traces back to the Latin word modestus, which means "measures appropriately" or "without conceit". It embodies the idea of propriety and humility, steering clear of excessive pride. As an English virtue name, Modesty belongs to the same family as Faith, Hope, and Charity, though it has always been far less common than those familiar names.
The concept of modesty has strong ties to religious and philosophical teachings. Saint Thomas Aquinas described it as "humility, studiousness, temperance in outward movements and in apparel". Variants of the name include Modesta (Latin/Spanish), Modestine (French), Modestina, and Modestia, with the nickname Mod often used as a shortened form. Historically, Modesta has had more recognition, ranking in the "Upper 43%" of given names, while Modesty itself remains a rare choice.
Modern or Classic Appeal
Modesty carries a timeless charm as a virtue name, yet its rarity in modern times adds an unconventional edge. Unlike more popular virtue names like Grace or Faith, Modesty offers a distinctive option for parents who value meaningful names that stand out. Its classic roots ensure it retains a sense of enduring character, even as it remains under the radar.
The name also ties into the broader trend of "Mo-" names for girls, which saw a surge in popularity during the mid-1990s but have since declined. By 2018, only 0.246% of baby girls received names starting with "Mo-", a 74.9% drop from their peak in 1995. This decline makes Modesty an especially unique and intriguing choice in today’s naming landscape. It blends tradition with individuality, offering something refreshingly different.
Popularity and Uniqueness
Modesty is not among the top 1,000 baby names in the United States, making it an exceptionally rare pick. By 2018, only four "Mo-" names appeared in the top 1,000, further highlighting Modesty’s distinctiveness. Its rarity aligns with the growing trend of parents seeking names that stand out from the crowd.
While its variant, Modesta, is more traditional, Modesty remains an uncommon choice. For those drawn to virtue names but looking for something beyond the usual suspects like Faith or Grace, Modesty offers a meaningful and original alternative that breaks away from mainstream trends.
8. Moana
Meaning and Cultural Origin
Moana, a name rooted in Polynesian tradition, translates to "ocean" in languages like Māori and Hawaiian. In Samoan, the phrase lanu moana refers to "blue", symbolizing the deep and expansive ocean. The name embodies the profound connection Pacific Island cultures have with the sea, reflecting their seafaring history and even appearing in local mythology as the name of a sea god.
While primarily used as a feminine name, Moana is occasionally given to boys in certain Polynesian communities, showcasing its versatility across genders.
Modern or Classic Appeal
Moana has always held a timeless charm in Pacific Island cultures, blending ancient traditions with a modern aesthetic. The name gained global recognition with Disney's 2016 film Moana, which brought its themes of courage, adventure, and independence to the forefront. This blend of cultural depth and contemporary resonance makes it an appealing choice for parents looking for something meaningful yet modern.
Popularity and Uniqueness
In the United States, Moana remains a rare choice, never breaking into the top 1,000 baby names. Its highest U.S. ranking was #1,555 in 2017, but by 2018, its usage had completely dropped off, highlighting its distinctiveness in the American naming landscape. However, the name enjoys more popularity in Polynesia, ranking #58 in Tonga and #160 in Samoa. This contrast underscores how Moana bridges global recognition with a uniquely cultural identity, making it a standout option for those seeking something both uncommon and meaningful.
9. Moriah
Meaning and Cultural Origin
Moriah comes from the Hebrew Mōrīyyāh, which translates to "seen by Yahweh". This name holds profound biblical importance, as it is associated with the sacred mountain where Abraham was tested and where King Solomon constructed the Temple of Jerusalem. The site is deeply respected across several religions, including Islam.
Although its roots are primarily Hebrew, Moriah occasionally appears as a variant connected to Irish and Gaelic names like Maureen and Mary. It has also been linked to the Greek term for "sacred olive tree". These diverse connections add layers of meaning to the name, making it resonate across cultures and traditions.
Modern or Classic Appeal
Moriah seamlessly combines its ancient biblical heritage with a modern, feminine charm. Despite its origins in scripture, the name feels surprisingly current. It first emerged on U.S. baby name charts in 1988, making it a relatively contemporary choice in America. Emmy Samtani, Founder of Kiindred, notes that Moriah symbolizes a divinely chosen place, embodying faith and reverence.
This mix of spiritual depth and modern sensibility appeals to parents looking for a meaningful name that stands out without being overly common. Moriah reached its height of popularity in 1992, when it was given to 517 babies per million, and it maintained a consistent spot in the top 1,000 names from 1988 to 2016.
Popularity and Uniqueness
Moriah is both rare and distinctive, reflecting its ancient roots and modern appeal. In the U.S., it currently ranks between #959 and #1,402, making it far less common than its phonetic counterpart Mariah. In 2023, only 8 babies in the UK and 10 in Canada were named Moriah.
While it remains uncommon in the U.S., Moriah enjoys greater popularity in Israel, where it ranked #85 in 2023. Notable individuals with this name include professional basketball player Moriah Jefferson and contemporary Christian singer Moriah Peters, adding a touch of modern relevance to its timeless appeal.
10. Montana
Meaning and Cultural Origin
The name Montana originates from Latin, meaning "mountain" or "the country of mountains". It carries imagery of towering peaks and vast, open landscapes. Its ties to the U.S. state of Montana bring to mind the spirit of the American West and a love for outdoor adventures.
Variants of the name include Montanna, Montina, and Monteene. As a name inspired by nature and geography, Montana aligns with modern trends that celebrate the beauty of the natural world.
Modern or Classic Appeal
With its connection to nature, Montana has a contemporary vibe that feels fresh and adventurous. Unlike more traditional names like Molly or Monica, Montana stands out with its outdoorsy charm. The name gained traction for girls in the late 1990s and early 2000s, peaking during that time before its popularity waned. Interestingly, its use for boys has seen a notable rise, with rankings improving significantly by 115 positions in 2018.
Popularity and Uniqueness
In the U.S., Montana is now a distinctive choice for girls. While names starting with "Mo-" were quite popular in 1995, reaching a peak adoption rate of 1.2%, that figure has since dropped by 74.9% to just 0.3%. This decline has made Montana a rare and unique option for parents seeking something less common. Its rugged and adventurous connotations make it an appealing choice for families drawn to names with a strong connection to nature and geography.
