Hi, Aayla and welcome.

What language are these names from, please? I'm sure they are Slavic and my guess would be Polish.
"Tchotchke" looks a bit like Russian but trinket in Russian is something like "balabolka" and "przewalski" has a 'w' in it, which is also not a letter/sound used in Russian - their nearest is "B", pronounced "V".

I'm immortal until proven otherwise
