death record JENSDATTER/KAROLINE B 1865.08.30

i am looking for a death record for JENSDATTER/KAROLINE KIRSTINE born 1865.08.3 in oslo. daughter of SAMUELSEN/JENS & TRULSDATTER/KAREN. she would have died before 1870.08, as another child of the above couple was born named CAROLINE. i suspect there was only 1 Caroline born in 1865, but the death certificate of the Caroline i know shows she was born in 1870. this means that either the various records (1865 census, death certificate, etc) are inaccurate, and that there was only the 1 Caroline born 1865, or there was a Karoline born in 1865 who died as an infant/child sometime between 1865-1870. any and all help is always appreciated!
