Each link will open the list of names found in that range, with year and county. Remember to think about alternate spellings, and that alternate spellings may be in different lists.
Counties marked with an asterisk no longer exist, but the notes may be helpful in determining if any records survive, and where they might be found. Not all counties are indexed yet, but the county name on each page is linked to the appropriate Family Search page, if that county is available online. Those that are not are indicated as such.
