I love Daphne, but I think of a dowdy woman with dandruff in late middle age, also Neighbours, Scooby Doo etc. It's a pity I think in another 20 years it will rocket in popularity.
I also love Rosamund, Rosalind, etc (see someone else has mentioned Rosalind here recently)but it seems always to inevitably become 'Roz' which I am not keen on. Any other short forms you could use?
Are 3 syllable names inevitably shortened. Can you think of any that usually aren't?
