Herman Amundsen, b. 1865, tinsmith in Bergen

Searching for descendants of Herman Amundsen, b. 1865 in Florø, married Barbra, living in Bergen in 1900 census with five children: Hildur, Borghild, Sverre, Herman, and Alf, born between 1887 and 1899. Herman's parents were Amund Torsteinson (or Tostensen) from vesle Dengerud in Aal, Hallingdal, and Marthe Berg from Mosterhavn. Amund was still alive when his brother died in the USA in 1914, but was dead by the time his sister died in the USA in 1925. Can't find him in the deaths in Bergen during that time period. The Dengeruds in the US have a reunion every other year, and it would be great to establish a transatlantic connection.
