Hi, one of the names of our shortlist is Thea. I am just wondering whiter it needs to be Dorothea or Theodora on the birth certificate? I am a big stickler for full names not nicknames as the "proper" name. I.e. I love Betty but would only ever have Elizabeth on the birth certificate. However, I am not sure I can pull Theodora or Dorothea off, if you know what I mean? For example, I am imagining family asking her name just after she is born and I would feel a little silly saying theodora but would feel quite happy saying Thea. Is it a proper name in it's own right? Thanks!
