Cornelia is a family name we’ve considered using. I love how versatile it is, having the formal option of Cornelia but also loads of nicknames.
Nicknames we’ve considered are Cora, Cori, Neely, Nelia, Nell, Nellie, Coco
What do you think of nickname options for Cornelia?
I think my favourite nn for Cornelia is either Nell or Cora. Some that weren’t on your list are Lia, Nila, Ellie, Connie, Ora, and Nala.
I love [name_f]Nell[/name_f] and [name_f]Nellie[/name_f] as nicknames for [name_f]Cornelia[/name_f]! [name_f]Cora[/name_f] and [name_u]Coco[/name_u] also work well. You might also like [name_u]Nori[/name_u], [name_f]Nora[/name_f], or [name_f]Nella[/name_f] 
[name_f]My[/name_f] favourites are [name_f]Cora[/name_f] and [name_f]Nell[/name_f]!
Cora, Cory, and Nellie!
[name_f]Nellie[/name_f] is cute. Corncob could be a really cute pet name 
[name_f]Cora[/name_f] and [name_f]Ellie[/name_f]
I adore [name_f]Nell[/name_f] and [name_u]Coco[/name_u]! [name_f]Cleo[/name_f] could be a cute stretch option as well, or [name_f]Cece[/name_f] for her initial.
[name_f]Nell[/name_f] is my favourite! [name_u]Coco[/name_u] is cute too!
[name_f]Lia[/name_f], [name_f]Cece[/name_f], [name_f]Nia[/name_f], [name_u]Eli[/name_u] maybe
[name_f]Cori[/name_f], [name_u]Neil[/name_u], and [name_f]Nellie[/name_f] are my favs 
Cora, Nellie, & Coco would be so cute! 
[name_f]Nell[/name_f] and [name_f]Nellie[/name_f] are definitely my favorites, followed closely by [name_f]Nella[/name_f] and [name_f]Lia[/name_f] — but I’d never considered [name_f]Cori[/name_f]! I like that a lot too. For [name_f]Cordelia[/name_f], one of my favorites is [name_u]Codie[/name_u], so [name_f]Cori[/name_f] is very appealing
[name_u]Coco[/name_u]
[name_f]Neele[/name_f] is my favorite, which is a short form of [name_f]Cornelia[/name_f].
[name_u]Coco[/name_u] and [name_f]Nell[/name_f] are my favourites
i like nell best !
