It's not a direct source on Anwen's name, just on her parents' name, but if they were both using Williams at the time, it's a reasonable assumption that Williams was Anwen's last name at this point. Using "Anwen Williams" instead of "Anwen (work name)" also prevents the discussion of whether Shrouded or The New World is her "first" appearance.

(Then again, two Williamses have had a non-Williams child before...)
