After the reappearance of the eldest son, I could see the rediscovery of Olivia coming a mile off! :-)

What does Olivia mean when she asks her father, "...why so cold a name, papa?" He's just called her several endearments, so this is a little puzzling to me, especially the reference to wisdom. I looked through the prior pages, and he usually thinks of her or refers to her as Olivia, or Livy, so I can't figure out what she means. I'm probably misreading this. Any ideas?
