Yeah. And then there was Gul Madred and Gul Lemec. That would have to be one very popular first name on Cardassia... Also, when do officers get called by their first name?! That would be like everyone calling Picard "Jean-Luc", rather than just Beverly, or everyone calling Sisko "Ben". Or aliens concluding that "Captain" must be a very popular name on Earth.
HA! There was a character in one of Gul Re'jal's stories that made a joke about exactly that.
