OP here
DH and I are still throwing names around.

I like Luca he likes Lucian (and you can spell it either way )
I don't know about trying to hard. My DH and I don't sit around thinking let's be totally different than out family/friends. Let's just be way out there! We just pick names we feel we like at the moment.
For someone who thought of Lucy - with my girls that was on the list

for one of them.
For those saying Satan or Lucifer. Never thought of that (glad we're atheists and won't be heading to church any time soon)
More than likely it may change. But maybe not. I'm a Libra and can never make up my mind ever! Even with food, decorating, clothes. My DH has just grown to accept it.
I don't seem to mind that Luca is not a nn to Lucian (loo shen for those who asked). I'm sure he won't mind either.
When and if we change our minds we'll be back
