Which do you prefer? I am a little put off by Matilda's popularity at the moment, but I don't know why as we live in the states and the name is #650 here.
We are due at Christmas, so I like that connection for Clementine. I am not a fan of the nicknames Clem or Clemmie.
I have a different middle name for each:
Matilda Erianthe
Clementine Elizabeth
