I think this profile is this person:
because even though the dates are different, the wives are identical.
I'm working through tree of a DNA match on Ancestry who shows:
Dempsey Powell
B:11 Mar 1755 Wake, North Carolina, United States
D:15 Oct 1808 Wake, North Carolina, United States
and the DNA match is from his wife Pleasant Benton and from the descendant branch of their daughter Martha (Powell) Fort who was born 1784.
So I think the dates of the link showing b. 1755 is the correct info.
