Rosen
Spook aristocrats love names starting with Rosen, like Rosenberg, Rosenbusch or Rosenbaum. This is a near-perfect pun with Semitic רוזן rwzn rozen meaning “prince”, “ruler”, “baron”, “count”. It’s commonly thought of as a “Jewish” name, but that’s just because rulers regularly feign to be “Jews”.
The name Rosen is an almost perfect pun with the Semitic title רוזן rwzn rozen, which means “prince” & “ruler”, and is also translated as “baron” or “count”. It is used in the Bible at Proverbs 14:28.
Combined with the suffix -Berg, a Rosen-Berg would then stand for a “veiled prince”.
Names without N could be instances of the Rose pun instead. The names are similar, but the Semitic pun-word is unrelated.
