I wouldn't call my daughter dash but it's up to you. We come from different countries so it might be nice for someone of your nationality but it wouldn't for someone of mine.
My 2 daughters are called: lucy-rose and beth
if I was to have another daughter(s) I like the names:
emma,emily/emillie/emilee/emileigh,ashlee/
ashleigh,serun,chloe,mia, kia,tia,louise,leanne,lauren,zara,isabel/i
sabelle,jordan,daisy,demi
