Nathaniel Gist - Nathaniel Gist - Uncle and Nephew Appear to Have Same Portrait

Please look at the profile photos for [Nathaniel Gist Nathaniel Gist], the uncle, born c.1707 and for [Col. Nathaniel Gist Col. Nathaniel Gist] the nephew, born 1733. They appear to be identical. I don't know which one is correct.

According to https://en.wikipedia.org/wiki/Nathaniel_Gist, the uncle and the nephew are often confused. The Wiki article did not have a portrait for the nephew, so I could not verify it that way. The source material found on the uncle's profile does not have any portraits, so I could not verify it that way.

Also, the portrait may not belong to either one of them. The nephew's profile photo has a source. If you check the source, it says the portrait is of someone else entirely!
