I think we've decided on Josephine if it's a girl. We haven't discussed middle names yet, but I like Katherine, Kate or Iva (my grandmother's name was Iva Katherine - she went by Kate).
For a boy, we're thinking Hudson, which has been on our list since our first pregnancy. It has increased in popularity though. Although we both really like the name Hawthorne, too. No clue on boy middle names.
