According to the household examinations Johan Severin left his family in Rålanda for America on May 5 1902. His brother Olle August left on May 6 1898. I found two more siblings, both born in Tegneby. Agda Josefina b. Aug 8 1893 and Gustaf Hjalmar b. Feb 1 1896.
Their parents Johan Martin and Johanna Sofia got married Nov 3 1878. Johan Martin died Oct 23 1914. Johanna Sofia died Jan 3 1933. Johan Martin died in an accident. According to the note in the church book a police officer confirmed it was an accident. It seems his carriage was knocked over somehow. Johanna Sofia died from brain hemorrhage.
There are some more information in the household examinations for 1903-1933 regarding the children and who they married etc. Not sure if you are interested in that but if you are let me know.
