Other Andreassen & Blomqvist's?

Greetings from Minnesota. Through the information available here I was able to discover the name of the ship that my Andreassen ancestors came to America in 1867. THANK YOU!! The Andreassen's were from the Kolvereid parish which was north of Namsos. The oldest brother of Christian Andreassen, Johan Andreassen, inherited the farm of Prestvik back in 1856. The Blomqvist's I have traced back to 1865 and at that time were in the Mo area. They lived in the Nesna area until immigrating to America in 1903. The families settled in the Baldwin & Woodville towns of Wisconsin. My question is this, how might I go about trying to contact some people in Norway that would be able to assist me in seeing if any relatives exist? I had discovered that the "white pages" for the areas in Norway also listed some email addresses. I wrote to several people that had their email addresses listed, but no one responded... Your help is greatly appreciated!! [:)]
