Siergiej

Siergiej is the Polish spelling of a Slavic name that Russia made its own. On official forms and in an urząd register you will also find the fuller variant, Sergiusz. The short meaning usually attached is "servant," yet Polish tradition pulls the other way, toward strażnik, obrońca: a guardian who stands watch.

Much of that protective sense gathered around Sergius of Radonezh, the fourteenth-century monk who founded the Trinity Lavra north of Moscow and became one of the most venerated saints of the Orthodox East. His fame carried the name deep into Russian life, where it later belonged to the composers Rachmaninoff and Prokofiev. The servant of the older meaning had become, in practice, a defender.

So the name holds both readings at once. A servant by one account, a guardian by another. Both survive. In Polish they sit together under Sergiusz and Siergiej, still marked on the calendar at the imieniny of Saint Sergius.
