I still think that it reads "braenobili" in this particular entry. However, as @erstwhile editor mentioned, it might mean "praenobili". In another entry (4. from the top) a "praenobilis D.na [Domina]" is mentioned.
According to Karl Ernst Georges: Ausführliches lateinisch-deutsches Handwörterbuch. Hannover 81918 (Nachdruck Darmstadt 1998), Band 2, Sp. 1864. (a Latin-German dictionary of 1864, < "praenobilis" means "vorzüglich berühmt" (exquisitely famous). This is a quite literal translation. In the end it just means "noble" as I already suspected.
