I like it. I think the story is a good association; I'd rather be named after her than
Ismene.
I like
Antigone Thalia- even though it's a bit too heavy on the Greek mythology to use.
I'm not thinking of many combos right now, but
Niamh or
Neve would be good. I also thought of
Ruth, but that's al litttle boring. I think it would work well with some Welsh names, but I can't think of any good ones at the moment :)
