Well we have different personal tastes in names so I don't know how much help ill be. I personally hate the name Helena. I know someone with that name and she doesn't like it either.
I think its a grandma name. Crystal just so happens to be my least favorite name along with Lily and Isabella. I love unusual names like Skylar and Fallon- willow is kinda up there with that.
And I think that Summer is really mainstream. Its a pretty name,but clashes with Louise. My moms middle name is Louise and her first name is Anne.
I no someone whos first name is Cami and her middle name is also Louise. I think those sound good. Gosh, I really don't know- Again, our preferences are different.
So my advice would be to go with your gut or maybe consider what YOU would want to be named out of those. Good Luck, Its a hard decision!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
