Ok so we found out yesterday we're having another little girl

I have no ideas what name to use as a close friend had a baby and used the name both DP and i had our hearts set on but these things happen right... Anyway we picked a different name for the reason we can shorten it to a name i like but doesn't sound like a name on its own and then i found out a close friend calls her DD that lol so not having much luck here and trying very hard not to step on anyone's toes or "steal" anyones names but not having much luck

If bub was a boy he would have had my grandad's name as his middle name and i would LOVE to name our little miss after my Nan but.... i just dont think we will her name's fairly old fashioned (Brenda Ursula Yvonne) I just don't know...

First names we like
Kaitlyn
Shay
Cadence (maybe)
Danielle (maybe)
Sheyanne

But i have NO middle names picked at all i know i have ages to go but i like to pick a name early that way if you decide you don't like it you can change it without too much trouble IYKWIM

Sorry that was a bit all over the place hope you can make sense of it.
Any suggestions/opinions would be greatly appreciated TIA
