Magnus, Hannibal & Samuel Longstrom

I am searching for three relatives that came to the U.S.A. from Sweden.Magnus (born 3/30/1890) was in the 1910 census in Thermopolis Wyoming and then disappeared. He originally was in Siverton Co. Hannibal (born 4/21/1858) was working with a painter, that is all I know.Samuel (born 2/16/1834) has disappeared since leaving Sweden.They all were born in the west of Sweden in Bullaren.Which is in Göteborg Bohuslän. Thank you. Jerry Longstrom jel@netvalue.net
