It looks like a form of
Ceridwen. I love
Ceridwen ^_^
This Cerigwyn looks like legitimate Welsh to me, though I don't know enough about the language to be sure..
I guess as it was in the paper, you don't know if she's Welsh? Just wondering, because
I don't see anything wrong with using names from languages without being from that country.
Ceridwen is lovely, and Cerigwyn looks like it'd be pronounced almost the same, so I like it too.
