[@DracarysBitch] barons might be in the sense of trade barons?  I don't know the answer to your queations, but I know ayz wanted something simple.  The patriarchy is a diffwrent nation/state than Hourglass is, so their ranks as well as their social structure are likely different.  I'm sure the hourglass nobles know who outranks whom, but my understanding is that for the purpose of simplicity the actual titles and forms of address are simply lord and lady.   (And if you actually use something else you're probably seen as snobbish)
