Ludvig and Andrine Arnesen

I can find Ludvig (Karl Ludvig) Arnesen in the 1900 census but not in the 1910 census? Family charts show him dying in 1913 and Andrine dying in 1912. I have never been able to find any records to support that. Now I am thinking maybe they died before 1910 since they do not show up in the census. What parish should I look at to find their death records? Any other clues anyone can suggest would be appreciated! thanks Census year: 1900 Municipality: Kristiania Municipality number: 0301 Street name: Calmeyergade 15 Ludvig Arnesen hf g MøbelSnedker for mestere 1835 Fr.stad Andrine Arnesen hm g Hustru 1834 Kristiania Jenny Arnesen d ug Datter 1870 Drammen Alfred Arnesen s ug Fyrbøder Tilsøs 1875 Drammen Agnes Arnesen d ug Kassererske v/Kolonialf. 1878 Fr.stad Christian Kallum el ug Hdlsbetj. v/Kolonialf. 1876 Moss Gudmund Sletner el ug Hdlsbetj. v/Kolonialf. 1877 Urskaug
