Not at all. It sounds like you're very young and/or desperate for a "unique" name. Liliana is good.
Giselle is good. Espinoza - BONK! WRONG!
However, Giselle and Liliana are very strong names to go together but they sound better to me if it was Liliana Giselle rather than Giselle Liliana. Edit: Again, I say that Espinoza doesn't go well with either name. But Giselle is too strong.
Lilianna/Liliana is a better first name. More.
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.
