Please be careful with what you pick up on FamilySearch: Kümerle and Kammerle may look pretty close to an English speaker, to a German speaker they are nowhere near being easy to exchange. Also, Oberschaffhausen and Ballmertshofen are about 200 miles apart, the first in Baden, the latter first in the Duchy of Pfalz-Neuburg, then belonging to the Dukes von Thurn und Taxis, then Bavaria, and finally to Württemberg.
