I love all three to be honest, and I have gone through phases where all three have been a favourite. I usually prefer
Anna as a nn for something (usually it is Andromeda...I think the fact that my
Andromeda could go by simple
Anna makes it a little less of a GP) so I will strike that one out seeing as nns are not an option in this scenario.
Anne is what my
Nana goes by (she is
Annette nn
Anne) so that is a very appealing option. I think
Hannah is sweeter than
Anne but both are beautiful in their simplicity. I would probably let my SO choose between these two if I really had to make the decision in real life. I just can't decide.
Today their combos would be
Hannah Calanthe and
Anne Clementine though
