I descend from Johann George Kasebier.
Agnes Casebeer
John George Casebeer
Christian Gottfried Kasebeer
Johann George Kasebier
John von Christophe Kasebier
Christophe Kasebier
Not being a German linguist I can't vouch for the variations of the surname,
but it does appear various family members altered the spelling ad lib, with
the Casbeers moving south, and the Casebeers holding in the original
Pennsylvania stomping grounds.
