Online Lyman Chalkley's CHRONICLES OF THE SCOTCH-IRISH SETTLEMENT IN VIRGINIA: EXTRACTED FROM THE ORIGINAL COURT RECORDS OF AUGUSTA COUNTY 1745-1800, is now completed. This three-volume series with more than 1,600 pages of extracts from early court records is completed. <http://www.rootsweb.com/~chalkley/>. I have looked through all 3 volumes for the surname FERGUS and there are no listings. This may save you the same effort. You may wish to search for other surnames. Happy (re)searching, Cynthia
