I can understand the urge to take one's lineage back to some landmark personage.
I don't think there is such an "urge" here. I didn't get that impression from the OP at all, simply that he wanted people to look for any possible errors.
One of my ancestors is a Benbow. All the Benbows seem to trace back to the same family, two or three members of which emigrated to the USA, so there is a lot of American interest.
My goal was to connect my branch to the main family, since nobody seemed to share my little clutch of Benbows. Eventually I did so by "killing off" a first wife, whose burial was buried in non-conformist records.
But further back there's not so much interest for me, as it's been researched to death by people hoping to trace their ancestry to the famous Admiral. He doesn't seem to have had any surviving sons, so good luck with that
