i actually heard of a BOY called Asher the other day. which i think was interesting too
Asher is an old Hebrew name PP (means blessed abundance) - up until quite recently I had only ever known of it as a male name.

Ashlyn is a lovely Gaelic name - the traditional spelling is Aisling (or sometimes Aislin), but it is commonly anglicised to Ashlyn. If you like it and think that it fits your family, who cares what others think.
