Some Degenhardts are from the same place as the Montags.

From the 1880 edition of The History of Fond du Lac County:

Jacob Degenhardt, proprietor of the Railroad House, Campbellsport; born in Kreis-Mullhausen, Kullstadt, Prussia, Sept. 6, 1832; was educated in the Fatherland, where he traveled nine years for a firm, selling woolen goods; came to America in 1857, locating in Grant Co., Wis., and attending the Platteville school two winters; was two years in the European Hotel, Milwaukee, then traveled a year, selling dry goods, notions, etc. He then married and settled on a farm in Ashford, also acting as an insurance agent; has owned and kept the Railroad House since May, 1874, having in connection a bar and livery. Married Mrs. Regina Mauel, by whom he has three children--Regina, Michael and Henry; Mrs. D. was born in Rhenish, Prussia, in 1826, her former husband, Bernhardt Mauel, leaving her at his death with a sixty-acre farm and four children--Anna, John, Frank and Margaret. The family are Roman Catholics, and Mr. Degenhardt is a Democrat, having been Supervisor three years, and Assessor the same length of time.

I just sent this and some other details to Lisa Jones, and I will post this a second time on a different thread from 1998 where someone asked about Jacob.
