Not having a go but...

"I wanted an opinion of the name not a big arguement about the way it is spelt!"
You asked for opnions on the name. Of the 65 threads 33 say that Eloise (Spelt without the u) is a lovely name, but with the u it is not as nice.
Two people said they liked it with the u.
The other comments varied from mentioning the book, the song and various other comments about the subject.
Given that you asked for people's opinions - that is what you've got - Eloise is lovely, Elouise is not. Fair enough if you don't agree with what the other 33 posters have written, that's your perogative - your child to name as you please, but if you ask for opinions - then you have to accept them whether you like them or not.
There's no argument here, honest, just people giving their opinions, and for once mostly in agreement with each other. Unfortunately, just not in agreement with you! But at the end of the day, whether you agree with the majority, or go your own way - it is your child and good luck to you. I hope you have a happy birth and baby, and whichever spelling you choose, the name in essence is lovely!
