Johanne's stephfather, Carl Brynildsen died Apr 30, 1872 in Aas (today Ås) and was not burried before June 23. No 11:http://www.arkivverket.no/URN:kb_read?idx_kildeid=5750&i...
The note after his death: Ved hængning (= by hanging) and a word I'm not able to read.
There is no online record of women who died between 1871 and 1880 in Aas/Ås. I have searched for Boel's death before and after this period and not found her so I guess Boel died one of those years or she might have moved.
