1900 census enumerators found Humphrey Bogart twice, once here in Ontario County, New York as shown and again with his family in Manhattan. Both images can be viewed on our site.
I've found several of my relatives (all non-famous), enumerated in the same census more than once. It does happen...especially if people are moving at the time, or working and still living at "home." In some cases, marital discord may be the reason great-grandpa appears as the "head of household" and as a boarder in a boarding house in a nearby neighborhood.
