Kaarto I found a death notice for a Siri (?) Andreas Andersdtr Hellesen b.1784, died April14,1834 and buried April 20, Bakklandet. She was 50 years old. Could this be Andreas Hellesen's first wife?
Is there any local census for BakklandetRosenberg Parish or Trondheim between 1820 and 1840? I am still looking for more information about Andreas Hellesen. loismann
Here is a long shot possible in the 1801 for Anders Hellesen. But maybe you already have this reference? In this same family there is a Povel (Paul) Hellesen and there is a Paul Hellesen aged 64 reported as dying about 19 July 1841 in a Trondheim newspaper. The death notice only says survived by his widow Karen born Hauan Hellesen.
