Hi,
I looked in Ancestry and FamilySearch under White and Robelia but didn't find her after the 1930 Census. She was 14 in that Census and if she married the next year I'm guessing there was a child involved.
I did find Clarence in a 1940 Census with a different wife.
There is a volunteer in Pepin County who will go to the courthouse, libraries and cemeteries. You'll find his/her contact info at
