History & Origin
Alyn names a river in north-east Wales — the Afon Alun — and the valley through which it runs; the district of Alyn and Deeside takes its name from it. As a given name it also reads as a slim respelling of Alan/Allyn, a Celtic name whose sense is debated ('handsome' or 'little rock'). Alan leans strongly to boys, and here the name is used for a girl; the routes are uncertain, which we note (said 'AL-in').
It appears only rarely for girls in the U.S. Rare, crisp, and unisex in effect.
