It's still early today, but yesterday I found out that a house lived in by a distant family connection (we're talking cousin-in-laws several times removed) in San Francisco in the 1930s (and is still standing) was built before the 1906 earthquake. I don't know much about architecture, but I like looking at buildings, and this fact impressed me.
Having a look in the local library (as you do) to see what else I could find out about the earthquake, I found a children's book that said the fire that followed caused more damage than the earthquake itself. It went into the details of the fire engines of the time and said that dogs were associated with fire wagons (pulled by horses at that time) because they ran along barking to warn people to get out of the way. This was new to me. I had wondered what the point of the fire dogs was. Were they dalmations? It didn't say. But the point is, a lot of the things I find out don't involve my relatives.
Okay, I admit it. Twenty-five words was an impossibly short limit!
