My files do not show any of the names that you mention, sorry.
You are fortunate to have made an ancestral connection to Austria. I have yet to find the European origins of my Neufer/Newfer ancestors. They "popped up" seemingly out of nowhere in Maryland in the 1790's (or before). All my Neufer/Newfer info is posted at my website.
