You are correct in Vrt*, but the only Vertachich I know of in the US settled in Ontonagon, Michigan. Have not traced any other male Vertacic to the US. Who are you descended from? There are Vrtachitisch's in Doblice prior to 1941. They were in several houses there. I assume Kocejve is the the former Gottschee, and not the village next to Crnomelj?
