Dick Eastman has launched a site for genealogical queries. Using a very simple interface, this is an online database that currently contains over 500 queries. You can search for any term in all of the queries, but they are also organized by surname and by location.
Perhaps most telling about the site is what it says it is most proud of: No fees! No spam! No invasion of your privacy! No account required!
