Sorry, although I don't have a lot of information on the Kuhn side of the tree, none of those names have come up yet. From the ones I have located the Censuses have their occupations listed as farmers and an electrician. This is a unique fact if you've come across this, the Kuhn family lived in South Africa for awhile also during the late 1890's and early 1900's before going back to Germany and then immigrating to the US. Any bells???
Good luck in your search!
