Welsh Unisex Names
Welsh unisex names work gracefully for a child of any gender. Welsh names come from Brythonic Celtic, one of Britain’s oldest languages, and carry a distinctive music and mythology all their own. Many draw on nature and character — Rhiannon (a legendary queen), Gwyn (“white, blessed”), Eira (“snow”), Dylan (“son of the sea”) — and appear in the medieval tales of the Mabinogion. Welsh spelling looks unusual to English eyes because it follows its own rules: ll, dd and w all sound different than expected. Lyrical, ancient and increasingly fashionable, Welsh names offer a Celtic alternative to Irish and Scottish that feels both rugged and poetic. Below are real Welsh unisex names, each with its genuine meaning, pronunciation and origin — researched, never invented, and honestly noted where the sense depends on the writing or dialect.

How Welsh names work
Welsh names come from Brythonic Celtic, one of the oldest languages of Britain, and they carry a distinctive music and a deep well of mythology. Many are nature and character names — Eira (“snow”), Gwyn (“white, blessed”), Dylan (“son of the sea”) — and a great many appear in the medieval tales of the Mabinogion. To English eyes the spelling looks unusual, because Welsh follows its own consistent rules, but those rules unlock a soft, lyrical sound that feels both ancient and fresh.
The sounds of Welsh
A handful of letters behave differently in Welsh. The famous ll is a breathy sound made by placing the tongue as for “l” and breathing out (as in Llywelyn); dd sounds like the soft “th” in “this” (Dafydd); w is often an “oo” vowel (Bronwen); f sounds like “v”; and u can sound like “ih.” Once these click, names like Rhiannon, Ffion and Aneurin read smoothly.
Myth and the Mabinogion
Welsh legend is a rich source of names. The Mabinogion gives us Rhiannon (a mysterious queen), Branwen, Pryderi and Gwydion, while other tales and early history give Arthur, Gwenllian and Owain. These names carry stories of magic, sovereignty and the old British world, which is part of their romance.
Welsh among the Celtic languages
Welsh, Irish and Scottish Gaelic are all Celtic, but Welsh belongs to the Brythonic branch while Irish and Scottish are Goidelic. That means Welsh names have a family resemblance to their Irish and Scottish cousins but a sound and spelling distinctly their own — a Celtic alternative with its own strong identity.
Choosing a Welsh name
Consider how the spelling will fare in daily life — some Welsh names (Megan, Dylan, Morgan) are effortlessly familiar, while others (Rhiannon, Ffion, Aneurin) proudly show their roots. Each name on this page includes a plain-English pronunciation and its genuine meaning, so you can enjoy the Celtic music with confidence.
Frequently asked questions
How do you pronounce Welsh letters like “ll” and “dd”?
Welsh has its own sound system: ll is a breathy “thl” sound, dd sounds like the “th” in “this,” w can be an “oo” vowel (as in Bronwen), and f sounds like “v.” So Llywelyn and Dafydd sound quite different from their spelling.
Are Welsh names related to Irish and Scottish names?
They are all Celtic, but Welsh belongs to the Brythonic branch while Irish and Scottish Gaelic are Goidelic — so they share a family resemblance but are distinct languages with different names and sounds.
Do Welsh names come from mythology?
Many do. The Mabinogion and Welsh legend give us Rhiannon, Branwen, Dylan and Gwydion, alongside nature names like Eira (“snow”) and Aeron.
