The Master Surname Index (not online) of the Alberta Genealogical Society lists some 10 Botten names among them are;
Gunhilde E. BOTTEN, 1864 - 18 Oct 1934
Halvor K. BOTTEN, 1862 - 14 Jul 1945
both buried next to each other in the Medicine (Diamond) Valley cemetery at Benalto.
I did not check for any of the other names.
