There use to be a fellow who would mark a rune and put it in a runebook for every home. I don't know if he still plays or still does this. I also don't know how extreme he went as far as naming them the homes etc.
They probably strung him up from a tree somewhere.

That's pretty much what IDOCrs do for castles.
I just use UOAutomap. Much quicker. Plus it aids in placement.
