The story of Arwyn
Gwyn is one of the most productive elements in Welsh naming — Gwyneth, Gwendolen, Bronwyn, Arwyn — and it covers white, fair and blessed at once, which is why Welsh names built on it are hard to translate cleanly. Arwyn is a genuine Welsh men's name. Its American use is confused by the near-identical Arwen from a well-known fantasy novel, which is a woman's name in an invented language, and the two have merged in the records.
Meaningscholars disagree
very fair, blessed
Welsh ar- is an intensifying prefix and gwyn means white, fair or blessed, so the compound reads as very fair. A second and separate influence is the invented Arwen of twentieth-century English fantasy, which is a different name in a constructed language and has affected American use of this spelling.

The Janica test
Every popular name lives one long story — a climb, a peak, a slow settling back. Arwyn's later chapters haven't been written yet, so we borrowed them: Janica climbed just as high around 1978, and its whole arc is on record. Line the two peaks up, and Janica's path sketches the road Arwyn is walking now.
