Very interesting, Justin.
I had hopes that "ansbachischer Herrschafft" was a illegible mother's name, but apparently not.
As far as I can determine, Ansbach and Markt Berolzheim are place names in Bavaria, about 160 km east of Lembach, so that could have been a possible prior residence.
Your right, though, there doesn't seem to be a definitive answer as to if there were one, or two, Johann Treibers. However, it seems odd that whoever was writing the record would, even inadvertently, begin writing "Weyl" in reference to the groom at a wedding, when he was probably standing right there. So, perhaps the writer thought Johann, the Butcher, (grooms father?) was dead, but then Johann, the Tailor, told him "Oh, no, he is still living in Markt Berolzheim (in the domain of the Ansbach rulers)"
I was also planning on ending work on this family line here, but now I might do some quick searches to see if there are records from Markt Berolzheim which might be able to shed some light on this family. There do seem to be a fair number of Treibers in Bavaria, in general, so with luck I might find something.
Danke schoen,
Michael
Edited to Add: A few searches have revealed that, in 1667, the village of Markt Berolzheim was purchased by the Principality of Ansbach, whose rules were the Margraves of Ansbach. So that confirms what you translated
I am not sure why that place would have been mentioned unless it was where the Treibers had once lived. The village was destroyed during the 1630s (Thirty-Years War, etc.), so that may have been a reason that some people left for elsewhere.
I have not yet been able to locate an online version of the Markt Berolzheim kirchenbuch, but I have seen it referenced on someone else's family site, so it does exist somewhere.
