 Regional historical investigations have sometimes confused Langenbach with a place near Baumholder, nowadays officially known as Berglangenbach, while the Langenbach with which this article deals was formerly sometimes called "Conken-Langenbach" (using an archaic spelling of "Konken").Among other things, this has thrown the year of first documentary mention into question.As author Helmut Weyrich from neighbouring Herchweiler pointed out, for instance, researchers Dolch and Greule give this date as 1385, when actually this may apply to Berglangenbach's first mention.
