Hi Kurt,
We have no info on Maria Guttenburger, other than her dob, and her parents names of John and Anna. Have never gotten anywhere with this branch of the family. Every once in a while I try again, but so far it a tall brick wall. Oh, I do have her spouses information, and their kids, but thats about it. Any info you might have would be greatly appreciated, and If I can look up anything for you, let me know. I'm pretty good at finding census info and other things. Anyway, hope you do well in your research.
Yvette
