Cheers that's a great help.  I am assuming the extra trusted.afr.volname-client- entries are left over from the removed peers,

Correct.

can I expect they will disappear after glusterfsd gets restarted?

They will remain, but it should not affect normal operation in any way.

I have a replica 3 volume I am using to serve my home directory.  I have notices a couple of split-brains recently on files used by browsers(for the most recent see below, I had an earlier one on ".config/google-chrome/Default/Session Storage/") .  When I was running replica 2 I don't recall seeing more than two entries of the form: trusted.afr.volname.client-?.  I did have two other servers that I have removed from service recently but I am curious to know if there is some way to map  what the server reports as trusted.afr.volname-client-? to a hostname?

Your volfile (/var/lib/glusterd/vols/<volname>/trusted-<volname>.tcp-fuse.vol) should contain which brick (remote-subvolume + remote-host) a given trusted.afr* maps to.
Hope that helps,
Ravi
