In Croatia, Herac families are Bosniaks by relative majority (from Podrinje (Bosnia) ), equally Croats (from Bakar ). In the past century, relatively most of Croatian residents bearing this family name were born in Podrinje, Bosnia (Visegrad area). In Holijaci in Podrinje (Bosnia) nearly every inhabitant had the family name Herac.
Prevalence
Only a few people with faimily name Herac live in Croatia today, in one household only. There were 10 of them in the middle of the past century, and their number decreased significantly. They are located in only one small Croatian place, in Skrljevo (<5).
In the sources analysed in the project Acta Croatica so far, the name is mentioned over thirty times, the first time 1902 in source Hartmann's General List of Apartments in Zagreb.
