Have you ever wondered how many websites are dedicated to genealogy on the internet?  Cyndi's List has kept track of most of them.  You can see all the sites she has collected by category at:

Genealogy Categories at Cyndi's List

She has collected almost 337,000 websites dealing with genealogy.  In the United States alone there are over 166,000 websites.  You can click on the link above and pick a state and then on a link to see any site.  This might help you find a group or person close to your research needs.  Seeing this list makes our site look pretty small.  I hope we can help our Sheldon/Shelden families find their ancestors.
