Yes, I know of the State Censuses (1885, 1895 and 1905). I heard some are available online at Ancestry. Also, my local Family History Center has some on microfilm.
Glad to hear we have a common ancestry. My records do show Hans Clemetson's wife as Marit Hansdatter Mork (Anna M. in most reports). Their two oldest children, born in Norway, were Karinius (Charley) and Anna. I don't have info on those born in MN or WI.
Alan, I appreciate the contact and the heads-up to avenues of research. If you think of anything else I should know to aid the search, post it here or contact me directly.
