So far, I've found my great-great-grandfather (in Alameda, Alameda, California), and my grandmother and her parents (in Chico, Butte, California) in the 1940 US Census. The best discovery? My twelve-year-old grandmother was one of the chosen few asked the supplemental questions. I think she'll get a kick out of that when I tell her.
