Charissa, Hans DeNuess(Neuss) is also my ancestor and I spent some time puzzling this out. This is what I came up with and I am pretty confident but not 100% confident that it is correct. Georg Neuss (1614-1678) had, best I can tell, 7 children. He named three of his sons Johann, Johann Conrad, Johann Georg, and Johann Jost. That seems unusual, but I know a contemporary man who has done the same and he calls them by their middle names. Also, Georg father was name Johann and perhaps he was trying to honor him. Both Hans and Jan are nicknames for Johann. I believe two of the sons Johann Georg (aka Jan) and Johann Jost (aka Hans) were Mennonites, be patient I will show you why I believe this. As Mennonites, bothe experiences religious persecution. Hans went to Holland to escape the persecution. While he was there, he changed his name to DeNuess to fit in with Dutch culture and he married. Jan married Elisabeth Lucken who was sister to the founders of Germantown in Philadelphia. So the two brothers and their wives went to Philadelphia to experience religious freedom in William Penn's colony which was established for that purpose. If you have an Ancestry account, my tree is public and you can check out all my sources. My most helpful source was: "William Penn and the Dutch Migration to Pennsylvania", which lists both Jan and Hans, specifically: Neuss, Hans, brother of Jan, Mennonite teacher,1698-1702, in Appendix C, of Dutch and German settlers in Germantown 1638-1709.
