Agnes Sandström and her daughters had been visiting her parents in Hultsjö and some friends in Forserum. They boarded the Titanic at Southampton as third class passengers. They joined a group of Swedish passengers led by Thure Edvin Lundström.
On the Titanic she and the children shared a cabin with Elna and Selma Ström. She told later that she did not believe it was real, when she was woken by a steward after the collision but she had gone up to the boat deck. The Ström family followed Agnes and her children but in the confusion on the aft well deck ladder she lost sight of the Ströms and never saw them again. She stepped with her children into lifeboat 13.
In New York they were sent to St. Vincent Hospital and continued their journey about a week later. She passed Chicago on 30 April. The Sandström family moved back to Sweden for good in the autumn of 1912.
There were at least three sons born to them after their return to Sweden; Vilhelm Leonard, b. 24 February 1913 at Forserum, Jönköping's County, Bengt Alfred, b. 13 December 1916 at Virserum, Kalmar County, and Lars Magnus, b. 9 September 1924 at Virserum. Mrs. Sandström passed away on 1 December 1985 in Sweden, aged 98.
