Ursula Schmenger, german movie director

Dear Sirs, the name of Ursula Schmenger as an director is somewhere wrongly written as "Schmanger". This last name doesn´t existand she never used this name as an synonym. I´m am very suer eabuot this information because of she is my mother in law and asked me to take care about the correction of the wrong written name. Her birthname also is Käthe-Ursula Becker, if interesting for some CV.
