Hi Piccadilly !!!
I read in comments that it means "river" or "winding" in Welsh but the database says that the meaning is unknown..what is the truth?
Aled is too close to
Alec in my mind.
I like
Alec so they are so similar that I can't see
Aled without thinking of a mispelling.
The obscure meaning (do you have more info?) makes it worse.
