I have seen Wulf's from Hasseluene who immigrated to Evansville, Vanderburgh
Co. IN. I have a Maria Wulf who immigrated in 1859 through the port of New
Orleans to Evansville, with Maria Feldhaus. Maria married in 1860 Gerhard
Plochg, whose mother was Margaret Wulf. I have seen other Wulf's and Koenig's
in the Catholic records of Evansville. Don't have anything else on them, but
there are Wulf's in the Hasseluene census records.
Hope this helps.
