Beatrice - my mother's name, and therefore my daughter's. I've just posted a long rant about its etymology on the Facts board.
Agnes - lovely with the French pronunciation, but no chance of that outside Francophone regions. As Aggies go, I prefer
Agatha, without the nn if at all possible.
Ursuline - like the Convents? No, really!
Ursula is already rather long and clumsy, and Ursuline adds pronunciation issues to the mix.
Michelle - I prefer
Michele or
Michèle (I have two friends, one English and one French, who use the two spellings), and would use
Michele as a mn.
Michelle, in spite of the Beatles song, seems heavy.
Tabitha - too feline by half; I far prefer
Talitha.
Greta - Quite nice , though I prefer
Margaret.
Greta is much nicer than
Gretchen,
Gretel and
Grethe, IMO.
Pia - very bland and, well, pious. I know of someone who named a daughter
Pia 'to honour his
Danish heritage', which I find unexpected.
