Mr Klas Albin Klasén 1 was born in Fliseryd, Kalmar, Sweden 2 on 17 July 1893.
He was the son of Klas Victor Karlsson and Johanna Matilda Jonsdotter (b. 1857) and was brother to: Karl Osker Emanuel (b. 1883), Alice Esther Amanda (b.1890) and Elin Viktoria Elisabeth (b. 1897). He grew up in Grimshult, Fliseryd and worked as a farm labourer.
Klasén boarded the Titanic at Southampton as a third class passenger (ticket number 350404 which cost £7, 17s, 1d). He was travelling with his 18-month-old niece 3 Gertrude Emilia Klasén and his sister-in-law Hulda Klasén. Hulda Klasen, a Los Angeles resident, was the widow of his brother Karl and Gertrude was the daughter of his sister Alice who, in 1911, had emigrated to Los Angeles and married Hulda Klasen's brother. Klas and his niece gained their emigration certificates on 22 March 1912 and they were travelling to be reunited with Gertrude's mother in Los Angeles. Also with them was another niece of Mrs Klasén's, Hulda Amanda Adolfina Veström, and they were part of a large party of Swedes that also included: Mrs Sandström and her two daughters, and Elina Olsson and Thure Lundström.
Both Klas, his niece and sister-in-law died in the sinking. Their bodies, if recovered, were never identified.
