Leupert in Schaffhausen SH

[awagenbach]

My ancestor Hans Martin Metzger (from Schaffhausen), married Margaretha Beusch( from Raefis St Gallen) 1716 in Schaffhausen. Martin was the son of Martin Metzger and what looks like Margaretha Leupert. I can't find any trace of the name Leupert in Switzerland. Does anyone have any idea where the name might be from? See the top right of the attached image.
