I found the report of the death (Dødsfallprotokoll) of Johanne Petronelle's stephfather, Carl Brynildsen. Second from top with date April 30:http://www.arkivverket.no/URN:sk_read/27487/36?size=full&...
The column after his name tells you his "Arvinger" (=heirs), but unfortunately I'm having problems reading it.
However I can not find Boel's name or reference to her so she might have died before him.
Here is what I think I can read in the column "Arvinger":
Slægtning i ? med ubekjndte Navne og ? ?.
(= Relative in ? with unknown Name and ? ?)
Maybe someone else can read the rest?
The one who reported about the death (next column) was Lensmand Stub. (Lensmand is the same as sheriff, I think)
Usually the one who reports about a persons death is a relative.
Here you have Claudius and Johanne with children in Oslo in the 1885 census:http://digitalarkivet.no/cgi-win/WebCens.exe?slag=visbase&am...
