The Sanborn fire maps can be interesting. Those for Pocatello list "Female Boarding House" for several dwellings in what was called then "The Walled City" because of the fence around the area. Seems like the local ladies didn't like seeing or socializing with the "ladies."

One place to look for interesting historical data on the ancestry of a house are old police records if such still exist and youn can get to them. Naturally, since about the 1990s most cop shops have gone to computerized record keeping, but the old books make fascinating reading if you can get to them.

I've seen ones for here! The first crime in Pocatello, Idaho in the Twentieth Century -- 12:07 a.m., January 1, 1901 -- wasn't murder, mayhem, drunkenness, rape, arson, a gunfight on Main Street! No! It was a drunk who was caught stealing coal from the Union Pacific Railroad yards!
