Thank you! Somewhere along the line, I found that she might have been from house 9, and so I followed all the mortality records for house 9. I then went to the index for "K" and tried to match up the pages, and late last night found one column that was very legible. (attached) To further complicate things, there were several cases of people with the surname "Kuna" in the house at the same time as the "Kundrat" folks.
The web says that Kun(d)rat means Konrad. The last 2 or 3 most recent records do say Konrad. But instead of Franz Konrad, they say Konrad Sklenarz. It's a mystery about the name change, but at least now I know that to find earlier records, I'll need to look under Kundrat instead. I've been working on this problem off and on for nearly 2 years, and it's nice to finally clarify it.
