Hi, Looking for any information on Jens Jorgen HANSEN, born 6th Oct 1874, bapt 30th Oct 1874, Notteroy. Married Martha Mathilde HANSEN 15th Feb 1903. Have found Martha going to USA to join husband at 28 Lake Street Manistee Michigan on the Oscar 11 21st August 1905. Dana Hansen sister/cousin joined him in 1906. Have found death of Jens 1934 Grotterod Sondre Vestfold. Would like to know when Jens went to USA, if Jens & Martha had any children and when they returned to Norway? Any help appreciated.
