It's possible that:
* The name is misspelled: Double check the spelling and try searching again.
* She works under a different name: Maybe she uses a stage name or has a different spelling of her name.
* She is not a well-known actress: She may be a lesser-known actress or someone who works in other areas of the industry (like behind the scenes).
To help me search more effectively, could you provide more details about Cara Van Wersch? For example:
* Any other information you know about her: Age, location, type of roles she plays, etc.
* Where you saw her name: Did you see it in a credit list, online article, or other source?
With more information, I can provide a better answer!
