The investigation of a heraldic mid-20th Century should have shown that the Rüegsegger s were originally from France of immigrant Huguenots, whose names were not pronounceable in the Emmental. They were replaced by field names. Rüegg was an old German word for "mountain" was that Rüegsegger thus the one who had his farm on the corner of the mountain. (All without any guarantee!)
