my husbands tree:
JamesNewt Johnson 1893 wife Martha Canup
James A.H. Johnson 1849-1933 wife Mary Ann "Polly" Cannon
James Anderson Johnson 1812-1898 wife Mary Ann "Polly" Piper
Samuel Johnson 1792-1858 wife Sarah P. Hightower

conflicting info from there:
William Johnson 1734-1806 wife Margaret Scott, not very likely since the info I have found says their Samuel was born in 1775. More likely,John Johnson 1750-1815 wife Elizabeth Ashfield, but not sure of that either. The James' and Samuel and wives are from family journals.
