I'd be fascinated to know how
German parents might pronounce
Myfanwy and
Anwen. :)
No idea about celebs as I don't know who most of them are! - but like
Megan and
Seren,
Anwen is short and simple, so I can see the possible appeal. Surprised by
Myfanwy though. It's very old-fashioned in Wales, so much so that I can see it getting a revival at some point.
