I believe all of the Wildenhaus and Wildenhouse folks in the US are descended from Johann Bernard Wildenhues, b. 1777, Heek, Ahaus and Maria Elisabeth Broeker, b. 1790, Averesch, Ahaus. (this info courtesy of Jim Scharf, WVScharf@aol.com). Those of the next generation who emmigrated were John Bernard Wildenhaus and Maria Elizabeth Wildenhaus. Gerhard Herman Wildenhaus possibly came to the US and then returned to Germany. His children, Gertrude Elizabeth Wildenhaus, John Theodore Wildenhaus, and Henry Bernard Wildenhaus, emmigrated. All were apparently from Wessum, Westphalia. I'm not too familiar with German geography, perhaps you can make something of these locations. It has been said that some of the family went by the name Broeker-Wildenhaus because the Broeker name held higher social status. My grandfather, John Theodore Wildenhaus, was supposedly smuggled into Holland and thence to America by his mother who was fearful after older sons had been killed in the Franco-Prussian War. I have put a Wildenhaus genealogy on RootsWeb's World Connect.
