I was first introduced to Behlsmühle in 1999 while visiting with Arthur Ellenbecker, the grandson of the Fassbender patriarch and immigrating ancestor, Peter Joseph Hubert Fassbender. As we sat talking with Arthur in his home – the very home that his grandparents purchased when they “retired” to Appleton, Outagamie, Wisconsin, he stood up to take a picture off of his wall. We immediately offered to assist him, but he brushed off the help stating that it wasn’t heavy, as he had dropped it a while back and the glass had broken.
Handing the framed image to us, he continued with the story. We had been talking about his great-grandparents, Johann Faßbender and Salome Barbara Bel. The image he handed us was a chalk drawing of the property in Oedekoven, Germany, owned by his maternal great-great-grandfather, Joseph Bel. Arthur told us that before his marriage, his great-grandfather, Johann, had lived in an apartment behind the “third upper window from the right.”
The property was known as Tempelhof Manor and the Tempel-Mühle (Temple Mill). Today, in 2021, the building is called Behlsmühle, for Joseph Bel. The manor, first mentioned in print in 1362, originally belonged to the Hospital of St. John and St. Cordula in Cologne run by the monks of the Johannites. The monks were descendants of the Tempel-Knights who operated many hospitals along the roads leading to the Holy Land and the Temple of Jerusalem.
The French conquered the Rhineland during the French Revolution. It was at this time they also confiscated the property of the churches and monasteries of the region. Over the next 20 years, they sold the property back to the German people to fund the war. It was at this time that Joseph Bel had the opportunity to purchase the property. The property included an oil mill, a 4-wing structure, a chapel, and a two-story manor house.
In 1812 Joseph Bel became Mayor of the 14 villages that comprised the Borough of Oedekoven. He held this position for two years. Joseph died at the age of 66 on September 12, 1837,  having spent his later years as a Gutsbesitzer, or “Gentleman Farmer.” 
Behlsmühle still stands. In 1984 the manor house was given Monument status. The plaque on the house reads: “Anna 1818 Joseph Bel.”  While the house and the mill’s wheel still stand, the rest of the property has been converted into a multi-family housing complex.
