Everton are pretty much the north side of Liverpool
Liverpool are the south end, give or take a few obvs
East Liverpool is mainly reds in Huyton, and erm Old Swan is like completely Evertonian.
There is no West Liverpool, just a river that acts as a sort of "wool moat"
As a Garston boy I can categorically stat that ain't the case....there were as many of us as there were of them.
But I am loving your description of the river as a "wool moat"....
