I would like to know a bit more about zone overseers, the office and its power. They seem to visit various branches (presumably each oversees 3 to 4 branches) to make sure everything is in order. The famous visit of Jack Barr to Ireland in the wake of the Ray Franz induced apostasy in that branch is an example of how a zone visit works.
I was intrigued to read in the Proclaimers book that in 1992 there were around 30 zone overseers, "including members of the Governing Body". This is interesting because it indicates that a select few non-Governing Body members have been given this special assignment that puts them on a par in a certain respect with those Governing Body members who also serve in this role. I suspect that only the younger Governing Body members serve as zone overseers since the traveling would be too much for the older ones. Aside from that, it would be really interesting to know if anyone has a list of non-Governing Body members who have been assigned as zone overseers over the years up to the present. In a certain sense, being assigned zone overseer is probably the highest ranking role a person could acheive in the organisation outside of being asked to serve on the Governing Body itself. So I wonder if appointment to this role historically is an indication of future further advancement onto the Body itself. Were those most recently appointed to the Governing Body serving as zone overseers before their appointment? If so, could the current list of zone overseers (if known) provide an indication as to possible future Governing Body appointments? Coming to think on it, are many zone overseers of the anointed? The Organized to do Jehovah's Will book makes no mention of whether they are anointed, so one presumes it is not a requirement and that most are therefore not anointed. If, therefore, very few of the 30 or so are currently serving as zone overseers are anointed, then that might mean an even stronger clue that those who are zone overseers and anointed may be future Governing Body candidates.
I wonder how many Governing Body members now serve as zone overseers. Presumably Carey Barber is too old, as is Jack Barr now, but what about the others - do they still act as zone overseers or is this yet another responsibility the Governing Body have shifted on to others in recent years?
