"In the 'old days' genealogical research was done by traveling great distances and then going through dusty archives or using microfilm readers. But the advent of the World Wide Web has changed that. Today much of the data useful to genealogists has been put on websites and can be accessed from the comfort of home.
"Unfortunately, many of these websites are not easy to use. And those that are don’t always offer all the versatility that is possible. For that reason I have created alternate ways of accessing some of these websites. In addition I have developed some of my own databases and programs to facilitate doing genealogical research. These are all collected together under what I call the One-Step website."
As a colleague noted, "It is not a sanctioned Census Bureau site, but the links it contains are very useful. In particular, if you click on the US Census Bureau, you will find a link to the 72 year rule, there is a great explanation of the reasons for it, and they are not what you are thinking."
