From what I can tell, the whole house used to be knob and tube, but the electrical system was updated at some point. The 2nd floor attic was unfinished, but they must've finished most of it at some point, so it's one big master suite. It looks like most of the wiring up there is new, and it all runs down to the main box in the basement. There is a junction box on my first floor, and it has a whole mess of wires in it. It appears that these power a lot of the lights on the first floor, and it looks like it's the old wiring running to those. I'm no electrician, but it looks like they ran one of the new lines up from the basement, and tied it into the old wiring with those twist-on connector caps. The live wire goes into a cap, with maybe 5 or so short lengths of new wire twisted in, then those short lengths tie into the old knob and tube. Not sure if this is the "proper" way for doing things. There is a bare copper wire in this junction box, and it looks like the old wiring ties into it.
Now downstairs at the main box, there appear to be two separate grounds coming out if (looks to be thick copper wire or maybe tubing). Anyway, one runs along the basement rafters, and the bolts onto the main water pipes. The other goes through a hole in the basement wall (below ground level)
