Kristian and Gunvor Persbråten f. Hamborg

Hello, having a bit of difficulty finding the death notices (Newspaper) or gravestones of the two. I think I am having difficulty because of the å in Persbråten. I also assume that both are dead. I also don't need anything else, nor their parents, or siblings. I just need their death notices, so I can see whether they had children. Gunvor Persbråten, adopted Hamborg f.
