How do I find out more information about grandparents who lived in Galicia while it was under the rule of the Austro Hungarian Empire ( mainly nineteenth century). I had ancestors specifically in Branow and Hivniv.

•Bezalel Drillich, Shlomo Drillich were from Branow
•Zalaman Klaughaupt, Shmuel rokeach from Hivinv
(Shmuel Rokeach was a big landowner, are there landowning records from the nineteenth century?)
