Liviu Librescu's Hebrew name, anyone?

In the old days in certain European countries like Lithuania and Romania, everybody needed their name to end with national suffix. For instance "Shvilli" in the Georgian Repyblic (Gruzye) and "ius" in Independent Lithuania. It seems like in Romania too, every citizen, whether Jew or Gentile, had their name end with "escu," as in Nicolai Caucescu. We see that Liviu Librescu, the Jewish Professor and hero to many at Virginia Tech University, kept his Romanian name, at least on his official documents. Rashag, son in law of the Frierdige Rebbe, signed his name for a while as Samarius Gurarius, in accordance with Lithuanian regulations, but we can easily tell what his real name was. I would imagine that Liviu is the Romanian for Leib, but what would the Jewish equivalent of Librescu

I understand that most of you have more important concerns; but this has the Tzig perplexed for days now.....
