My grandfather, John Sockaci(Socaciu) was close friends with a Nick Chelemen. My grandfather was from Soard near Sighisoara.Nick and his wife, Gisela, were god parents to my father and uncle.Per the baptismal record, Nick was listed as being from Sighisoara. My grandfather settled near Ellwood City ,PA and the Chelemen's lived there for a time also. Nick and his family then moved to New York City and then to Miami,FLA.Nick had a daughter,Florence. We do not know any more about her.I had research done in Soard and my researcher took picures of graves in the Orthodox cemetary there. There are Chelemens buried in the cemetary. I don't know if any of this information will help you.Good luck with your search.
