Ernst Heribert Björklund was born on 1 March 1894 in Skeppsholm, Stockholm, Sweden.
He was the son of former NCO (non-commissioned officer) Carl Johan Björklund (b. 20 August 1846 in Karlskrona) and Erika Kristina Johansdotter (b. 11 January 1850 in Långemåla) who were married on 10 November 1878.
He had five known siblings: Johan Emil Helge (b. 13 December 1877)(1), Carl Eugene (b. 2 November 1881), Jarl Harald (b. 2 November 1883) and Elsa Viktoria (b. 10 July 1885)(2) and Gurli Carolina (b. 7 September 1887). Ernst lived with his family at Grefgatan 62 in Stockholm.
His brother Harald had first migrated in 1901 and lived in New York; he made a return home in the summer of 1911 but later returned to the USA; it was Ernst's intention to follow him and settle, with the promise that work had already been arranged for him. He departed from Göteborg on 5 April 1912 aboard the Calypso and boarded the Titanic in Southampton as a third-class passenger (ticket number 347090 which cost £7, 15s).
Ernst Björklund died in the sinking and his body, if recovered, was never identified.
The Mansion House Fund paid 875.52 Kr (£48) to his parents with a further 911 Kr (£50) damage claims paid on 29 June 1914. His parents remained in Stockholm and his mother died in 1928 and his father in 1934. His brother Harald apparently remained in New York and eventually became a US citizen in 1922.
