Yeah, I was considering Dorothea too. I'm not overly concerned with nicknames - if I had a Dorothy or Dorothea I'd probably end up just calling her by the full name. As for yours, I get Dodie but Daisy feels contrived (sorry!). "Evil is human, it always has been." - Edward Buchan, Whitechapel
No need to be sorry! I'm just generally a fan of nicknames, especially as they're reflective of language, and Dodie really got me considering Dorothy more.
