Margaret, The information you have given, is very interesting and opens new possibilities, for finding the family of Joseph Guess who married Constance Taylor,in Caswell County, North Carolina,1787. The Mebane and Sharmon/Sherman family married into the Goss family (a close spelling to Guess) in Granville Co., NC and these family groups,lived in the same area, dating back to the 1750s or 60s, or earlier. Do you know the app. year Robert Lytle came to the Orange Co., NC area?? Do you have any thoughts on the surnames of families , who may have migrated, to NC with the Lytles and Mebanes?
