Overall the Lahnstein family has remained very popular with fans, thanks to viewer's favourites Claudia Hiersche (Carla), Wolfram Grandezka (Ansgar) and Verena Zimmermann (Nico) and the involvement with other popular actors like Miriam Lahnstein (Tanja) and Yvonne Burbach (Cécile).
Maria took the identity of her late sister Francesca to secure her place in the Lahnstein family, made an enemy in Ansgar's wife Tanja von Lahnstein (Miriam Lahnstein), was almost killed by Tanja and then tried to kill herself and Ludwig von Lahnstein (Krystian Martinek) in a fire.
