The funny thing when you're doing genealogy research is that you can search diligently but fruitlessly for, quite literally, years trying to find the tiniest clue, the key you need to unlock another generation of long-deceased ancestors. And then one day a random Gooogle search pulls up page 934 of a 1257-page
tome from its public domain archives and suddenly there it is, the piece you've been looking for:
It turns out this document's on Ancestry as well now; I assume it's a fairly recent addition to both since it's never shown up before. For a tiny paragraph it's remarkably informative, though: it gives me the marriage location, details of the parents and siblings, and a good idea of where I should be looking next. On the downside, the way the book's written makes it somewhat impenetrable in getting further information out of it, which is a bit of a shame when there's a letter in the Appendix from one Count Ferdinand von Hoechstetter of Austria that indicates that that particular branch is likely traceable all the way back to 1390.
