I love the name willow and Fern as well. Darcey is getting to be quite a popular name around us.
We have always gone the route of all four of us writing down suggested names, then the others cross them out until we end up with a couple (or in Kira's case, just one). The downside of this is that no-one finishes up with their 1st choice, but that said Taz's name suits him (he can be a real tasmanian devil). The other names i had for Kira were Roxy, Gina and Keisha. Had i have had a pedigree papers before we named her i think i would have gone with Mysty (Kendici Mystical Shadow)
you must be so excited though - can't wait to see some photos
