Dear List, Does anybody on the list know of any male Johnson who is a straight-line- descendant of Isaac Johnson, ( b. 14 Apr 1761 , Craven Co. NC & d. 18 June 1839 Davidson Co. TN)?      This particular Isaac Johnson was a Rev. War Vet, and is buried in Cane Ridge Cemetery in Davidson Co. TN.  Would like to find a male Johnson descendant who has had a YDNA swab. Any assistance appreciated! Thanks, Judy in TX
