My issue is it is a derivative of another name therefore does not have its own meaning - I like names that have their own meaning its just a "thing" with me.
in one way or another, most names are a derivative of another somewhere - whether it's the feminine version of a masculine name, a regional variation of another name... i guess what i would be doing is looking at the original name from which it is derived. if the meaning of that name appeals to you, you're happy with the way the names sound together, run with it! it is very hard to find original names that aren't "out there" now lol.

I would love to use Louise as the middle name but DH doesn't want to because it was Nikita's middle name - my reasoning is if we hadn't gone through what we did, this little bundle would never have been here and it would be nice to "honour" Nikita's memory by giving Beanie her middle name.
have you thought about having two middle names xxx xxx louise? to honor Nikita while you're new DD still has her own identity (two names of her own kwim). DD's has two middle names - one that is hers, one to honor her angel siblings
