Does everyone think [name]Lola[/name] would make a sensible nickname for [name]Caroline[/name]?
It’s a huge stretch, but pretty much anything can work as a nickname. To make it easier you could maybe do [name]Caroline[/name] [name]Louisa[/name] or [name]Caroline[/name] [name]Lavinia[/name] or something. I’ve heard of [name]Lola[/name] as a nickname for [name]Charlotte[/name], too…
I think it works.
In my opinion, [name]Lola[/name] has always been a nickname for [name]Lourdes[/name] so it’s a stretch to use it for [name]Caroline[/name]. My fav nickname for [name]Caroline[/name] is [name]Caro[/name].
Definitely a stretch! But like irisrose said, anything can work as a nn if you really want it to. I like [name]Carrie[/name] as a nickname for [name]Caroline[/name]; I also know a [name]Caroline[/name] that goes by [name]Lena[/name].
I think it is fine! [name]Coco[/name] is my favorite [name]Caroline[/name] nickname though 
As far as nicknames I think anything goes. People will call her what you do. It is a little bit of a stretch, but like another poster suggested you could always use another L name as a middle name to help tie it together. But really, if that’s what you want her nickname to be, then so be it!
