Candace rather than Candice!
Why do Americans take regular names then misspell them?
Another eg Natosha
Not sure if you're aware of this but this has happened all throughout the world for as long as people have had names.
For instance: Wilhelm (German)
Will/Willy (Anglo-Saxon Nickname)
Bill/Billy (Anglo-Saxon Nickname)
Vilhelm (Danish, Norwegian, Romanian, Swedish)
So just so you're aware, this isn's something that's solely attributed to Americans. Every culture does this.
