If you have ancestors from West Virginia, you should take some time to visit the West Virginia Pioneers website. While the majority of the site's data is for Jackson County, this free genealogy resource still has a lot to offer for those researching other West Virginia counties.
One of the resources you can expect to find on the site is links to books on Virginia and West Virginia. These links take you to other websites where you can read some or all of the book for free online.
Tracing ancestors through the time where counties were constantly having their borders changed to allow the emergence of additional counties is difficult. With West Virginia, you have the added confusion of it being part of Virginia until it gained statehood in 1863.
