We lost track of Severin after he disappeared suspiciously. He was born on Nov 1889 in Minnesota. His parents were: Olaf Kristiansen Bunæs, born 08 Apr 1864 in Bunæs, Eidsvoll, Akershus, Norway. Died 1939 in Gordon Twp, Todd, Minnesota, USA. Sigrid Gudmundsdtr, born 22 Jan 1870 in Stenmo, Stordal, Meraker, Norway. Died 1939 in Gordon twp, Todd County, Minnesota, USA. Severin married Aagot Tostensdatter Hansebratten on 17 May 1912 in Grand Forks County, ND, USA. She was born 05 Mar 1891, Ål, Hallingdal, Buskerud, Norway. Died 1950 in Saskatchewan, Canada. Aka Agnes Buness, Agatha. 3 children: Palmer Norman Buness, born 15 Feb 1913, Park River, Walsh County, North Dakota, USA. Died 24 Feb 2010, Oak Bay Lodge, Victoria, BC. Grace Eleanor Buness, 25 May 1914, Fordville, Walsh, North Dakota, United States. Died 11 Feb 2007, Spokane, Spokane, Washington, United States. Beulah Buness, 03 Mar 1917, North Dakota, USA. Death unknown. Severin's side of the family has been a mystery, along with his suspicious disappearance from the Van Hook, North Dakota area, possibly around 1922. Van Hook was a fair bit south of Minot, and is now underwater as a result of a big hydro dam project. All records were moved to a place nearby called New Town. Severin had two brothers, Melvin and Gilman, who at one time ran a hotel in Minot, North Dakota with Severin. It has since been torn down. Have scanned census info, social security and more. He may have wanted to disappear, so not really sure where else I can go for info. Thanks. Kevin
