So I really like [name]Kizzy[/name] as a nickname, but I am not so keen on Kezaiah.
Are there any other ‘full’ names that could use [name]Kizzy[/name] as a nickname?
Well, it’s a stretch, but [name]Cassandra[/name]?
Well, you could do [name]Kaziah[/name] without the extra a.
Carenza or [name]Karenza[/name]
[name]Cassia[/name]
Kishar
Kitini
[name]Kirsten[/name]
[name]Kira[/name]/[name]Keira[/name]
[name]Kinsey[/name]
The usual spelling is [name]Keziah[/name].
[name]Katherine[/name] [name]Zoe[/name] could be a [name]Kizzy[/name].
Some of these might be a stretch, but here’s all the names I can see [name]Kizzy[/name] working for. Some have KIS instead of a Z since it’s virtually the same sound (like [name]Izzy[/name] from [name]Isabella[/name]) or CIS since K and C make the same sounds usually:
Kiziah – light of heart
[name]Kisa[/name]
Kishi
Kisima
[name]Kismet[/name]
Arcis
And I like the suggestion of a K first name and a Z middle name, which seems like the best bet. [name]Katherine[/name] [name]Zoe[/name] is a nice suggestion or [name]Kassandra[/name] [name]Zinnia[/name] or some such.
[name]Kizzy[/name] is a stand-alone name since the 70s, when the show/book ‘Roots’ became popular.

My cousin’s name is [name]Kenia[/name] and I call her [name]Kizzy[/name].
I know a girl named [name]Mackenzie[/name] who gos by [name]Kizzy[/name].
[name]Katherine[/name] [name]Zola[/name] or [name]Katrina[/name] [name]Zoe[/name] would be cute.
I know a [name]Clarissa[/name] and her NN is [name]Kizzy[/name] and that is all she goes by 
[name]Kezia[/name] is a variant of [name]Keziah[/name] popular in UK/Commonwealths, pronounced kez-ee-ah, which I like better than kez-eye-ah. I know three here in [name]Oz[/name].
Ketsia (keh-tzee-ah) is a Hebrew transliteration.
[name]Keisha[/name] is another option that’s semi-related.
Kizurra is a Sumerian name meaning “sharp edge”
[name]Kinzley[/name] or [name]Kinsley[/name]?
