I know this has nothing to do with Alabama but...

Try the following:

Backtracks Geneaology Service of Glad Spring, VA
The Virginia Historical Society
The Virginia State Library
The Historical Society of Washington Co. Virginia
The Division of Vital Records in Richmond
Holston Valley Trails (not sure they are still in print)

By the way, the town is spelled Abingdon. Good luck with your search.
