Hehe, thanks for replying! I wonder if I could get away with
Aderyn on a boy, instead? The Welsh side of my family (who I don't really talk to about names, hence my asking here) are/were very proud of their heritage, so I wouldn't want to undermine the language. Hm.
I agree with you on
Hartwin, it has a lovely sound and appearance, but I don't know how I feel about it as a given name.
