I am also a Wombacher decendant. Barbara Ann Wombacher was a sister of my great grandfather. I have several documents, (i.e. obituaries, marriage and death records, showing that Barbara Ann Wombacher/Wombaker of Fillmore County, MN was the daughter of John and Anna Wombacher/Wombaker.
I too originally thought I was a decendant of Andrew Paul Wombacher, but have since learned that my John and Anna came to America separately from Andrew Paul Wombacher's family. They may have been relatives, but the connection would have been in Germany, not America. There are lots of names shared by both families and it's easy to think they are the same people. To make things even more confusing parts of both families settled in Minnesota.
I'm convinced that Barbara Ann Wombacher of Fillmore Co., MN was married only once. Her obituary lists her as Mrs. John Wratz and does not list children from other marriages. Other records confirm the idea that she was only married once.
I'm sorry to say I believe your information is inaccurate, however I have a fair amount of information about Barbara Ann Wombacher and her family that I am willing to share with you and everyone else. Please let me know if you're interested.
