Old houses are hilarious like that. House I lived in for most of my college career was a 100+ year old boarding house. The electrical outlet arrangement wasn't too crazy, but the way the circuits were wired was insane. 2 100A feeds from the grid, each with its own circuit panel. From there, absolute madness.
Three 2nd floor rooms, one on the opposite sides of the house from the other two, share a 15A circuit with each other AND a room on the 3rd floor (which is not directly on top of or near the other 2 rooms). This circuit is constantly being tripped by peoples computers/heaters. Guys run beefy extension cords to other circuits in the house.
One 2nd floor room has 2 20A circuits that it shares with no other rooms in the house. Thankfully I lived there and stored all my bitcoin rigs in there back when I was mining
There are a few other circuits that boggle my mind, zig-zaging throughout the three story house connecting multiple rooms up and down floors and across hallways. Then there are the few rooms with their own circuits. Thankfully all the outlets are grounded (They are three pronged plugs, never used an outlet tester on them.. so the ground plugs could just be for show..)
Old house and electrical wiring = lol
With those lols comes some terror though. At one point one of the sub panels went horribly awry and created a ground loop. The panel box got super hot and wires started melting. It also caused weird things like turning a switch on in one room turned someones lights on/off. The electrician was at our house for hours reverse engineering the mess that was that panel.
