Just received this info and thought it might be of use to you. I'm searching for info on Martin VanWig (Vanvig) of Trondheim.

Copy and paste this link for the 68 Wanvig`s who left Trondheim between 1867 and 1930. Note that additional spellings are Vanvik and Wanvik. The vig/viig spelling is older Norwegian.
