About spelling. I suppose the name has been translteraded in order to keep the pronounciation. My guess is it was "Cultas" (with Romanian "tz"). I am a native Romanian but for me it sounds like an adapted Hungarian name, while the ending "-as" which I suppose it pronounces "-ash". Try also searching "Cultas" in http://whitepages.rohttp://whitepages.ro in West Romania (Translylvania).
