discovery in 2004:
“Just found a mention about your family in one of my books. Apparently there is a Pandzic family in Tomislavgrad who originate from Drinovci near Grude. It says they are a branch of the Glavaš family. In the 1741/42 registry of Catholics, Fra Pavo Dragičević recorded two Glavaš families in Drinovci: Martin and Ante with 17 and 7 members, respectively. In the 1768 registry, Fra Marijan Bogdanović found two Glavaš families as well: Martin and Andrija with 44 and 11 members, respectively.
In 1795 when the parish of Drinovci started to maintain it's own metrical books (i.e. maticne knjige) you start to see the surname combinations Glavaš- Pandžić and Pandžić-Glavaš. Ante Glavaš, who was mentioned in the 1742 registry, carries the Pandza nickname but, in 1768, his son Andrija is seen carrying the Pandžić name.
Pandza, the nickname of Ante Glavaš, is not related to the surname Pandza which is found in Goranci near Mostar and originated from the old Karapandzic family.”
Pandza translated means "Claw", so Ante Glavaš was given the nickname claw, however his son Andrija carried the surname "Pandžić" and not Glavaš which essentially means the nickname was carried by Andrija to the now surname Pandžić forward from 1768.
