The Bell of San Gabriel...question!

Hi there. If you have seen the Season 1 episode, "The Bell of San Gabriel", I have a question. I have spent a lot of time searching online to no avail.

There is a character named Isabella, she is the potential love interest of Miguel. He later ends up as a Franciscan monk.

There is an actress who plays Isabella as a young child, Melody McGowan. She is credited on IMDb.

However, there is also a short scene of an older Isabella, as a young woman, an absolutely stunning brunette. She is in shock that Miguel wants to give up his inheritance to become a monk.

Does anyone know who this actress is? I have tried Google, Youtube, etc. and I can't find anything about her. Unlike other Westerns like The Rifleman and Laramie, I can't find a fansite on Death Valley Days.

Does anyone know who she is? She made quite an impact on me and I would like to see if she acted in other shows/movies.

Thanks for any help.
