I am assuming Germans but could be Norwegians who joined the German army ? I think it might have been before 1920?
Johanne Petronella's mother was Boel Marie Johannedatter and her step father was Carrl Brynildsen- they both died in Korsegaaden Aas in 1872 therefor I assume Johanne would get their home etc.. I dont know I Carl was previously married or had any other children ? Perhaps he had some sons that joined the army & then came back to Norway?
Johanne was deaf and went to deaf school in Oslo-she married In 1869 to Claudius Magnus Pedersen..
There is a family story that the family had a farm called Allen or Ahlen-not sure if this was in Aas or Idd where Johanne Petronella was born in July 1846
That is about all I know- sorry
