English and German, though not descended from Latin, both have undergone considerable Latin influence because of Latin's importance in religion and later in scholarship.

Romanian may very be an exception, but I have to admit that the development of Romanian national identity (and language) is not terribly well understood by me. I'd imagine Thraco-Dacians speaking populations were still active in Romania and the rest of the Balkans during the middle period of the Empire though. And though Romania is presently an Orthodox nation, at the time it had fallen under the influence of Latin, whereas the souther Balkans had fallen under the influence of Greek. This situation of course changed by the Dark Ages.
