You are welcome. Here is the information for the great- grandparents of Pierre and Marie Madeliene...
Pierre’s great grandparents and earlier generations:
Hans Wolf SCHWOERER, and Christine Agnès ANDRES (parents of Antoine Schwoerer) My direct line
Hans Wolf is also seen as Jean Wolf and Johannes Wolf. Christine is the daughter of Michel Andres and Apollonia Krieger who we call the mythic couple because almost every member of GenVerrE descends from them some way.
and Jean Martin WALTER and Anne Marie STENGER. (parents of Anne Marie Walter) The Walter family I am still working on. Suffice it to say you descend from one of the lines that starts with Peter Walter and his wife Anna Stenger that goes back to the 1600s. He is the son of Adam Walter and Barbe Betz. Adam is the son of Peter and Anna Stenger.
Jean Martin is the uncle to my 4th great grandfather Georges dit Chambre Walter who wrote a history of the glassmakers in the 1700s. There are some issues in this line as there are multiple men and women in the same towns at the same times who are cousins, or other relations and often someone picks the wrong one. I work with multiple people on this line and we are still figuring out some of these relationships.
Marie Madeleine’s great grandparents generation:
Jean Martin BURGUN, and Anne Odile FEISTHAUER (parents of Adam Burgun) My direct line. I have data on the Feisthauers that goes back to the 1400s in Austria. Georges dit Chambre’s mother was a Burgun. She is your Adam’s sister as her parents are also Jean Martin Burgun and Anne Odile Feisthauer.)
Adam WALTER, and Anne Eve SCHWOERER. (parents of Barbe Walter) Anne Eve Schwoerer is the daughter of Jean Wolf Schwoerer and Christine Andres so is the sister of your Antoine from above. The Adam Walter she is married to is son of Jean Nicolas Walter and Barbe Braun. He is the grandson of Adam Walter and Barbe Betz and the nephew to Jean Martin listed above.
I am running out of time tonight. I will try to send you files I have on the Feisthauer / Festor line
And some info I have on Georges Schwoerer. But both are very large and I will try to send them and what I have on the Walter line that is not 100% validated yet to your personal email if I can find it.
Also the Andres family is very documented and complex. That is a study unto itself.
My direct lines are the Walter Stenger lines, the Andres Schwoerer lines, Burgun Walter Feisthauer Lines.
So yes we are definitely related several ways!
