Oh, I thought I had read some of the Rootschatters from Australia mentioning that they had searched more current records than we have available, probably misread or misunderstood what they were saying.
However, Ancestry.com has US census records on line from 1790 to 1930 inclusive. I don't know how much information is available on the very old ones, as my subscription doesn't let me look at the US censuses.
