Hub, disregarding the elephant connection, DD2 had a friend called Celeste when she first went to sec. school - she was gorgeous but, it has to be said, a bit of a madam, so I wouldn't be keen (but who cares what I think )
Of the others recommended I love Estelle & Delphine...what about Pascale? Not a flower but a very pretty name I always thought.
My French exchange at 16 was Martine - not a flower at all...
