Olaf Martin Olsen was born 17 February 1885 in Homer Township, Langford, South Dakota. He was christened 29 March 1885 at Brule Creek Lutheran Church in Elk Point, South Dakota.
His parents were Ole Andreas, a farmer (b. 5 September 1846, d. 1926), and Anna Jacobsdatter, (b. 10 August 1862 at Etne, Hordaland, and christened at Gjerde the same day). They had married 6 April 1883 at Gjerde, Hordaland's County, Norway. They had come to the USA in 1883, shortly after their marriage.
Ole M. was the oldest of nine children. His known siblings included Anna Julia, b. 28 September 1886, Joseph, b. June 1888, Martha Olena, b. 18 May 1890, Serena, b. 1 January 1893, Severen, b. 23 May 1895, Engebert Christian, b. 9 November 1898, Ander ''Andrew'' Ovid, b. 8 October 1900, and Myrtle Serine, b. 10 January 1905.
As an adult he moved northward to a homestead in Broderick, Saskatchewan, about 60 miles south of the Province's Capitol, Saskatoon and just eastof the Saskatchewan River. Ole would help with work at the local grain elevator in Broderick when not doing field work.
Following harvest, Ole used to spend the winter months with his family in Langford, South Dakota. However, 1911 was to be an exception. He decided to spend the winter visiting his grandmother, Anna Johannesen Birkenes and other relatives in the Sunnhordland region of Norway. Ole intended to be back in Canada in time to begin spring ploughing in April.
Olaf ''Ole'' had been to a visit in Skjarsvik, Sönhordaland, Norway and was returning to his home Langford, South Dakota (c/o Ole B. Olsen).
He boarded the Titanic at Southampton as a third class passenger (ticket no. 265302, £7 6s 3d).
He died in the sinking and his body, if recovered was never identified.
