Kull Family Genealogy Forum
I can trace Gottlieben's ancestry back 9 generations in some lines. The complete list of her discovered ancestral surnames includes: Kull, Aechtler, Rapp, Ochner, Knoeller, Hamann, Greul, Schonhaler, Hammols, Kappler, Dalinger, Bodamer, Reister, and Benkeiser. Gottlieben's husband's family has additional names, of course, and most or all of these families are from the general vinicity of Neusatz in the northern Black Forest.
I do not know if Knoeller was Americanized by some of the family to Kneller, but it certainly seems likely.
Thanks for asking.
