There were Tomazic families living on the farm of Grize for at least 400 years and their direct decendants are still living there today. Approximately 150 years ago there was a change in family surname, because there were only daughters in the family and one of them was married to Jo e Zupancic who moved in.
Tomazic family is still present now.
From here some of the family branches has spread to the neighbouring places, to Vir, Maribor, Zagreb and abroad, mostly to Germany. However there are chances to locate some further ancesters of the oldest known Gregor Tomazic, because only few miles from Grize there is located the famous old monastery of Sticna. I will try to benefit from this fact.
