We went ahead and located baseball great Honus Wagner in the 1920 census as well. He is living on the same street as 1930, but the house number in 1920 is 605 Beechwood Avenue while in 1930 it is 615 Beechwood Avenue. Nothing major, but just remember that people do occasionally move and house numbers do get changed. And of course, sometimes street renumberings are done solely to confuse genealogists..... ;-)
Of course, you can search the everyname index to the 1920 United States Federal Census for your own relatives.
