Facts and Events
Five lineages on Ancestry identify the wife of James Cowan, son Andrew Cowan and Mary Walker, as "Bestey Doherty". This points to his father as being Person:Andrew Cowan (5) of Jefferson County TN. This is supported by a Jefferson TN Marriage record at Ancestry
Tennessee State Marriages, 1780-2002
Those lineages usually give James DOB as from 1770-1780, and commonly give his DOD as 1798 rather than 1841. This suggests that James Cowan=Betsey Doherty is a different couple than the one who died in Meigs County. None of these lineages suggest any children for this couple, consistent with a DOM of 1796, and his death in 1798.
Given the Jefferson County POM it seems likely that wife of James son of Andrew Cowan=Mary was indeed Betsey Doherty, and that this James died relatively young without descendants.
