Unfortunately nowadays an unterestimated because actually very nice and beautiful, to be used FN.
I appreciate the European version or use in the form of
Dorothee or
Dorothea.
The NN of this are Doro or Thee resp.
Dora. As well Dodo, almost a little foolish.
Occasionally sometimes may also be used
Thea.
The NN
Dottie is not really my case; sounds a bit old-fashioned and old-school for me.
