A large number of these paths are fake paths created by undocumented (and possibly false) genealogies uploaded by GEDCOM from popular genelogies during WikiTree's "wild west" days when anything went. Now we're in the era of clean-up.
Paths with uncertain ancestry such as you've found should be high priority for clean-up. If you're pre-1500 certified, they should be high on your "public service" list of profiles to document, and connections to correct, even though they may turn out unrelated to you. If you're not pre-1500 certified, you can still offer useful comments on their profiles with additional sources which may shed light on the person and the person's parents, spouse(s) and children.
The end result we should all hope for is that when WikiTree offers us a path to a possible ancestor, all of the links will be marked "confirmed". But there is a ways to go yet!
