Unique name need for post vasectomy baby girl!

So we got pregnant on a post successful vasectomy. I didn't discover this pregnancy till we were 24 weeks. I feel that this baby girl deserves a very well thought out and meaningful name. My husband and I I are at odds on this one- so we need some help! His go to is either Fiona or Klara and mine is Vivian which means alive. I want it to be very special because she's a 1 in a million odd! Thanks.
