I've just come across your post from 2000 and wonder if you found more information. I believe this Wilhelmina JAHNKE is my 3d great grandmother and married into BOLDT family. I am posting another website I believe is same connection but have not found any Waldo names.

http://freepages.genealogy.rootsweb.ancestry.com/~stanjoy/Bo.... I have been unable to connect directly with its author.

I am becoming familiar with Rock County in Janesville, Milton Twp., (Cole, Nelson) and am just learning about Edgerton but am seeing the area more and more. My Cole/Palmer line is in New York, Wisconsin and Brookings, South Dakota.

Would love to hear back from you.
