I only have one listing for a brother for Clara/Klara Gaugg. His name was Joseph Gaugg, b. 17 March 1798 in Dachberg Nr. 8, and d. 17 February 1876 in Dachberg Nr. 8, Maria Rojach parish. He was married to a Maria, last name unkown, on 16 May 1820 in Dachbert Nr. 9, Maria Rojach parish.
My email address has changed since the earlier posting.
