Looking for John Christenson

John Christenson was my great-grandfather and the story she was told is that he was the youngest child in a large family in the shipping industry. Knowing he would not inherit anything he stowed away on a family ship to immigrate to the US. According to a 1910 Census his immigration year was 1895 and he was 38 years old. He married Anna Nordstrom in 1902 in Chicago, Illinois, USA and had 4 children. He died in 1914 when my grandmother was only 4. I only have 1 picture of him and can't find any information on his family. If anyone had any information or could stear me in the right direction I would really appreciate it!
