> There was one ep of DS9 where we got to meet Quark and Rom's mother. Of course, the reason they had to go see her was due to some horrifying rumours (that proved to be true) that she had started wearing clothes and was secretly engaging in profitable business activities.

Quark and Rom's Moogie is a fairly recurring character. I believe that she is the only Ferengi female to appear, because all Ferengi women are never allowed to wear clothes nor aquire. Moogie is the exception.
