It's possible you might be thinking of someone else, or the name may be slightly different.
Could you please provide any additional information, such as:
* Possible misspellings: Are you sure the name is "Moya Fenwick"?
* Other details: Do you remember any details about the projects she was in, like the genre, time period, or any specific characters she might have played?
With more information, I can help you find the actress you're looking for.
