Serbian or, Particularly, Croat? As Much As I Love Kevin...

Over my dead body on this one. The Kvet-Kovits Rusznaks were not Croats, or even Serbs or Slovenians. First, the original name would have been "Cvetković" pronounced "S-vet-kovi[t or c]--a far cry from "Kvetković" (which is pronounced "K-vet-ko-vits") or "Kvetkovits". Second, only the Jews fled from Constantinople in droves or were particularly targeted for expulsion and murder--Christians were exiled by choice or force, too, or murdered as well; but not like the Jews. In fact, Jews fled Constantinople at least two times--once under Leo III, the second time when Constantinople fell to the Mohammedians.

Besides, the Rusznaks did marry fellow Anusim--Elizabetha Molnarová (Gyorgy Kvet-Kovits Rusznak) and Mária Novákova (Jakub Rusznak). Furthermore, Anusi families can exist and have existed as Anusim for centuries, and the Kvet-Kovits-Rusznak family existed as such from about 1848 (at least until here in America, I--so to speak--burst our bubble)--roughly, within three (the 19th-21st) Centuries and for a century and three-and-one-fifths scores (164 years, 1848-2012).
