OK, not problem right? Wrong, because other than 2 lightbulbs (incandescent) and 2 outlets that have nothing plugged in, I can't FIND anything on circuit 18!! I KNOW, there MUST be more - and that I'm missing something, but like a LOT of old houses, I really have NO idea exactly what is on circuit 18

Yes. I'm not familiar with it, but I've seen a device that puts a low
level signal onto a circuit. Then the circuit can be traced using a
probe. It can show the route within inches from one end to the other as
well as branches. That is the total sum of my knowledge of that device.
