I hope nobody minds if any of their hard work got left out of the update reply...
Just thought since this one seems to have a direction, maybe we'll take the ball & run with it. If any clues end up pointing another way, we can redo it...or if it stays on track, we can just copy and paste it and add new infomation.
I do not know the districts on the BMD so when they say "from" or "up to" I follow the blue links to see what the registration districts were before, or next.

so I am a nincompoop...but not a total one!
