Welsh Name Generator
Welsh names preserve a Celtic register distinct from Irish or Scottish - Rhys, Dylan, Bronwyn, Olwen, Gwyneth, Cerys. The phonetics carry double consonants (ll, dd, ff) that look strange to English readers but feel ancient. Many trace to the Mabinogion and pre-Norman Welsh tradition.
Example output: Rhys Llewellyn · Bronwyn ap Hywel · Dylan Davies · Cerys Morgan

How Welsh Names Work in Fiction
Welsh names come from a language where w and y are vowels and ll is a single sound English lacks, which gives names like Gwenllian, Llewelyn, and Rhys their distinctive look. Historically Wales used a patronymic system, ap (son of) and ferch (daughter of), and the fixed surnames that replaced it collapsed patronymics into forms like Price (ap Rhys) and Bevan (ab Evan), leaving Wales with famously few surnames: Jones, Davies, Williams, Evans dominate.
That surname scarcity is a gift to fiction: it explains the Welsh habit of distinguishing people by occupation or place (Jones the Post), a device that instantly signals a close-knit community.
Frequently asked questions
›How do you pronounce Welsh ll and dd?
Ll is a voiceless lateral fricative, closest to "thl" or a hissed L. Dd is "th" as in "the". So Llewellyn is roughly "thlue-EL-in" and Dafydd is "DAH-vith".
›Are these names tied to the Mabinogion?
Several are - Rhiannon, Branwen, Pryderi, Gwydion, Math come straight from the Four Branches of the Mabinogion (12th-century Welsh prose). Useful for Arthurian or Celtic-fantasy fiction.
›How do Welsh names differ from generic Celtic?
Welsh is Brythonic Celtic (P-Celtic), distinct from Irish/Scottish Goidelic Celtic (Q-Celtic). The two branches diverged around 600 BCE. Welsh names use ll/dd/ff and have a different vowel structure than Gaelic.
