Hello Lauri, I don't have an Agnes Nancy BARNETT JOHNS(T)ON in my files but I do have Barnetts who lived in Wilson Co., TN and Warren Co., TN in the 1790s and later. Also there are Barnetts living in Independence, Jackson Co., MO in 1830s. The family members I have are not JOHNS(T)ONS but have similarities in names. Mary Boyd's name caught my eye as my gg grandmother is Sarah Boyd BARNETT. There are also the names: Martha, Mary and Robert. I will gladly share any of the family groups with the dates and places I have. Peggy Wood Lewis
