I found a baptism record for Kurilish family in which it lists the place of birth for Tomo Kurilich as Krajkovici Hercegovina
or at least that is what I think is closest to the translation. Tomo Kurilich had on his WWI draft card that he was from Trebinje So I am thinking krajkovici would be close to Trebinje. I am wondering if anyone is familar with that village or the Kurilich family from that area.
