Master Karl Thorsten Skoog was born in Iron Mountain, Michigan on 13 July 1900.
He was the eldest child of Wilhelm Johansson Skoog (b. 1872), a mine engineer, and Anna Bernhardina Karlsson (b. 1866), both Swedish immigrants hailing from Skaraborg who had emigrated to the USA shortly after their marriage in 1898. He had three siblings: Mabel (b. 1902), Harald (b. 1906) and Margit Elizabeth (b. 1910). The family appear on the 1910 census living in Mountain City, Michigan and his father was described as a miner and he worked at the Pewabic Mine as an engineer
At age seven, young Karl was involved in a railroad accident near his father's mine. A carriage severed his left leg and the toes on his right foot were later amputated, damaged beyond repair and he used crutches for mobility.
The family decided to return to Sweden around November 1911 which they did but soon regretted the move and made plans to return to America. Having travelled via Stockholm, Göteborg and Hull, the family boarded the Titanic at Southampton on 10 April 1912 as third class passengers (ticket number 347088 which cost £27, 18s). Travelling with them were two relatives, Elin Pettersson and Jenny Henriksson, who they had persuaded to join them.
How young Karl coped on the night of the sinking on crowded, sloping decks will remain unknown. Karl, along with the rest of his family, were lost and their bodies were never recovered.
