I mean, the Romulans' homeworld and its sister planet are named after ancient human myth.
Excellent point. As Serveaux points out it could've been coined by humans, however. Same for Vulcans, in fact.
Offhand, it looks like I made an observation about one-syllable sounds, and you replied with an example involving at least two syllables.
The number of syllables is not very relevant to the point I raised. Given the huge number of cultures, you could end up with much longer names that happen to be the same as an Earth name... but for the audience it would still be weird.
Colt is an English name.What does "English" have to do with it?
