[Callers] Who're all the whos?

Back in 2008 I wrote a dance to celebrate my first year of contra dancing and Chris Weiler was kind enough to go through it with me. In doing so I heard my first mention of the Who-What-How Much format for dance description. I'm working on a personal project where I'd like to be sure I've identified all the "Who" roles in that model. For my purposes, I'm doing this in the context of contras, traditional squares, triplets, family dances, etc. (but not necessarily English, Ceilidh, Scottish, etc. - though I'm not closed to gathering any that may exist uniquely therein). I've listed below what I've collected so far from my personal cards deck review & research through several published works. Are there any Whos I've missed? Please note: I've deliberately left the primary role designation for last as I wish to avoid rehashing that topic once more. Let's please just accept there's a designation for the primary roles and agree they'll be determined by circumstance and conscience, as fits a given dance community. Thanks! Don ROLE DESIGNATORS - "WHO" Partner Neighbor Corner Opposite Everyone (All) Center/End Shadow/Trail Buddy Couple Top/Middle/Bottom; Ones/Twos, etc.; Heads/Sides; First/Second, etc. (var. of Couple or Primary Role) Travel Buddy (4F4) Active/Inactive (is this distinctly required, or is it always an alternate name for another role var., e.g.: 1s?) Neutrals/Ends (var. of Couple or Primary Role) Ring of N (4,8, etc.) And of course... Primary Role (Lark/Raven, Righty/Lefty, Lady/Gent, Talls/Smalls, etc.), in plural or specific variation (e.g.: Talls, Raven 2, End Lady)
