So because of the sheer number of mentioned characters in Rose's St. Olaf stories alone, I started a list of unseen Golden Girls and Golden Palace characters.
The format for filling out the list is provided in the page overview, and there's three pages splitting up the alphabets so the pages don't get too long...well, longer than they're gonna be already. St. Olafians already have their own separate list, so they don't need to have a lot of info on this one. Just a link to the St. Olafian residents page is good enough.
I'm also putting together a Google Doc to pile all these characters up, and I also have a somewhat-finished document of episode citations that I'm working on if anyone wants access to those to help out!
