Welsh · “Derived from the Welsh elements "tal" meaning "brow" or "head" and "iesin" meaning "shining" or "radiant" — together meaning "shining brow". This was the name of the great semi-legendary 6th-century Welsh bard who is credited with the earliest surviving Welsh poetry.

Gawain

Welsh · “Derived from the Welsh name "Gwalchmei", meaning "hawk of May" or "hawk of the plain", from "gwalch" (hawk) and "mei" (May) or "mei" (field). Alternatively derived from a Brythonic form meaning "white hawk". Sir Gawain is one of the most important knights of the Round Table in Arthurian legend, nephew to King Arthur and known for his legendary courtesy, honour, and prowess in arms.

Welsh · “Welsh form of the Late Latin "Ambrosius", from the Greek "ambrosios" meaning "immortal" or "divine", from "ambrotos" (immortal).

The name carries associations with prophecy, hidden knowledge, and sacred power.

In Welsh mythology, Bran the Blessed (Bendigeidfran) is a giant king of Britain who possesses a magical cauldron capable of restoring the dead to life. In Irish mythology, Bran mac Febail is the hero of an early voyage tale, sailing to the otherworldly islands of the west. The raven was a bird of prophecy and the battlefield in Celtic tradition.

The name projects a brooding, intense quality.


More Welsh names

Cynddylan

Derived from Welsh elements, probably "cyn" meaning "chief" or "first" and "dwylan" possibly from "dwylaw" (two hands) or from a personal name — giving a heroic meaning along the lines of "foremost in battle". Cynddylan ap Cyndrwyn was a 7th-century Welsh king of Powys whose death in battle against the Northumbrians is lamented in the elegiac poem "Canu Llywarch Hen", one of the earliest surviving Welsh poems.

Cynfael

Welsh compound name from "cyn" (first, chief, before) and "mael" (prince, leader), meaning "first prince" or "chief prince". The name appears in early Welsh genealogical records and belongs to the tradition of aristocratic Welsh compound names that project authority and precedence. It has the elevated register of a name given to heirs and eldest sons in the medieval Welsh noble tradition.

Efnisien

Derived from the Welsh "efnys" meaning "troubled", "restless", or "discord" — the name is essentially programmatic, defining his character in the story. Efnisien is one of the most disturbing figures in Welsh mythology, the troublemaker of the Second Branch of the Mabinogi whose unprovoked mutilation of the Irish king's horses triggers the catastrophic war between Britain and Ireland, though he ultimately redeems himself through self-sacrifice.

Osian

Welsh form of the Irish "Oisín", meaning "little deer" or "young fawn", from the Old Irish "os" (deer) with the diminutive suffix "-ín". Osian is the standard Welsh spelling of the name borne by the legendary Irish poet-warrior, and it has been popular in Wales since the 18th-century Ossian poems of James Macpherson sparked a pan-Celtic literary revival. It remains widely used in modern Wales.

Tegwen

Compound Welsh name from "teg" (fair, beautiful) and "gwen" (white, fair, blessed). The combination creates a double emphasis on radiant beauty and purity. The name belongs to the tradition of Welsh compound feminine names and carries the same root as names like Gwenllian and Branwen, placing it firmly in the medieval Welsh naming tradition.

Rhiannon

Possibly derived from the Old Celtic title "Rigantona" meaning "great queen" or "divine queen", from "rigan" (queen) and a divine suffix. In Welsh mythology, Rhiannon is one of the most important figures of the Mabinogi — a sovereign goddess associated with horses, birds, and the Otherworld who endures unjust punishment with superhuman patience before being vindicated.
