I am from Malterdingen about 20 km from Schmieheim. The origin of the Schmieheim Sexauers is as far as I know Malterdingen. I have not much about my Sexauer branch, because my grandfather Sexauer died in World War II as well as his brother. One of his sisters emigrated and the other two sisters were married in other villages, so I havn't heard much of the family history on this side. There were Sexauer Family meetings when I was a child and I guess the invitation was from a Schmieheim Sexauer, so there should be a relation between my Sexauers and the Schmieheim Sexauers. In his familybible my greatgrandfather wrote, that the name of his father was Friedrich. But I also have a copy of my Greatgrandfathers birth record, that says his father's name was GEORG Friedrich Sexauer. I am trying to contact my uncle (my mother said he knows more, also because he lived for years in Schmieheim) If your informant should be a lady with name Devenny, we should have at least a common anchestor (try Hans Georg Drick with wife Wickersheim on familysearch) but from an other branch - the mother of my fathers mother.
