Welsh is one of the oldest living languages in Europe, and Welsh names carry centuries of history. Dylan (from Welsh dy llanw, meaning 'son of the sea') reached #64 in England and Wales in 2024. Rhys means 'enthusiasm' and has been a consistent top 50 name for decades. Seren — meaning 'star' — is rising fast for girls.
Welsh names are distinct, elegant and unlikely to cause classroom clashes. Even the most popular Welsh names are far rarer than English equivalents — a real advantage for parents who want something meaningful but not generic.
