I am looking for information as to ethnicity of this name. Leonard or Leonhard Goudhaire appeared near Cologne in 1690's (died 1724) and built Schoss Bensberg for Jan Willem Kurfuerst von dem Pfalz. He married Catharina Becker in 1703 and remained near Bensberg building Haus Steinbrecke for himself. He had a daughter, Anna Maria, and 3 sons: Wilhelm, Joannes Petrus, Johann Heinrich. The last name in baptismal and marriage records was mispelled Gutherr, Goidthair, Goidthaire, Goithaire, Guthaire, Gudhaire, Guthair, Gouthar. I suspect it may originate in what is now Belgium.
