I think he is a person that has been "created" over the years. I see him all over the internet, sometimes attached to [[Washington-366|Richard Washington]], or [[Washington-187|John Washington]], along with how he is attached today on Wikitree. I never see any supporting evidence that he even existed.
While we cannot delete profiles, because he exists in so many family trees, I would just mark up his profile as being "uncertain existence" and disconnect him. That way, if someone else tries to add him, they will see the notes and understand the research done to date.
