Do documents from 3rd country need to be translated?

[aulus]

My ancestor passed through a 3rd country on the way to the US. As a precautionary measure, I have obtained certification of no naturalization from that country so that there will be no doubt that he was still an Italian citizen when his children were born. Do I need to have it translated into Italian and/or English if I am applying at a consulate in the US?

if the kids were born there etc then yes all documents must be translated because it would be an important document. if it was literally a place he stayed on his way to the US and no one was born there and no marriages etc. then the italian consulate wont even have a way of knowing he was in this third country.
