Yes, my Hrabaks lived in several villages in the same area as your Hrabaks including the village of Jivina. Jivina is only a few miles from Chesnovice (Cheznovice). I am in touch with others doing Hrabak research and I would be happy to put you in touch with them. My other connected surnames are: Franta, Balej, Ungr, Anyz, Cerny, Strnad, Vodrazka, Vajner, Ekl, Ernest, Humelhonza, Fajrajzl, Kopp, Holman, Opatrny, Hanzal, and Kriz. Do you have any of these surnames connected to your Hrabaks?
