Hanovii Comitis longum hoc testabitur Classroom, Praeside quaeque ipso Curia suit fuit. Testis Lauterius fame generosus avorum ....", or even in the early 1600s in a tombstone citing: ". .Stephanus Lauterius, prior secundus .. "and which corresponds to the Germanic Lothar, we recall the Frankish king Lotarius grandson of Charlemagne.
