The Rhenish networks behind the Dülcken family
Behind the world-famous harpsichords and organs of the Dülcken family lies a fascinating network of eighteenth-century Rhenish elites. New historical and genealogical research sheds light on how the Dülcken and Knöpfel families became intertwined through the geography of the Rhine and the structures of the Protestant faith. A reconstruction of a strategic alliance between Sankt Goar and Weisel at the beginning of the 18th century – with the influential Lehr family serving as the crucial, connecting link.
Mention the name Dülcken, and one immediately thinks of the refined instrument making in Antwerp, Brussels, or Amsterdam. However, the roots of this influential dynasty lie further inland, in the German Rhineland and the County of Sayn-Wittgenstein-Berleburg. To understand how Johannes Daniël Dülcken (1706–1757), his sons, and his grandsons were able to develop into esteemed instrument makers, we must examine the close-knit network that their ancestors established along the banks of the Rhine at the turn of the eighteenth century.
The Lehr Family: The Common Denominator
The deeper explanation for the Dülcken family's presence in the distant, right-bank Rhenish village of Weisel lies in the homeland of their ancestors: Bad Berleburg. For a long time, the marriage of Georg Ludwig Dülcken (Johannes Daniël's father) on October 13, 1704, in Weisel to the mysterious Johanna Margaretha remained a genealogical puzzle. Why would a pastor from Wingeshausen travel all the way to the Rhine to wed?
Recent research demonstrates that the connection was primarily familial rather than geographical. The key lies with the influential Berleburg family, Lehr.
Georg Ludwig's father, Eberhard Dülcken, had married Maria Magdalena Lehr in 1664, daughter of the former Berleburg mayor Andreas Lehr.
Simultaneously, the family of Pastor Johann Jacob Schramm (the respected minister in Weisel) was also closely tied to this very same Lehr lineage through marriage (Anna Catharina Lehr).

The Stiftskellner and the Opposite Side of the Rhine
Following their establishment in Weisel, the paths of the Dülckens clearly intersected with those of Johann Conrad Knöpfel, an absolute key figure in nearby Sankt Goar. On the opposite side of the river, Knöpfel held an influential double role as Stiftskellner (financial and administrative manager of the Protestant Stiftskirche) and Proviant-Commissair (provisions commissioner) of the strategic military fortress, Burg Rheinfels.
Even though the Rhine posed a physical barrier, the administrative and economic lines of the village of Weisel ran directly to Knöpfel’s estate office in Sankt Goar. The Stift (foundation) held ancient Zehntrechte(tithe rights) in Weisel. Farmers were required to surrender a tenth of their harvest—a logistical process overseen directly by Knöpfel. Furthermore, the parish of Weisel depended entirely on the administration of this Stiftskellner for the maintenance of its buildings and the pastor's stipend.
Social Class and the Knöpfel Connection
In the early eighteenth century, the pool of potential spouses within the Protestant (Evangelisch-Reformierte) elite in the Rhineland was small. Peers sought each other out to keep capital, influence, and social status within their own circles.
The intensive administrative and economic relationship between the Stiftskellner in Sankt Goar and the church community in Weisel laid the groundwork for the next generation. It was Johannes Daniël Dülcken himself who capitalized on this network by marrying Susanna Maria Knöpfel, the daughter of the Stiftskellner. This strategic marriage fused Berleburg intellect with Rhenish capital and administrative prestige.
Conclusion: A Foundation for Generations
What initially appears to be a series of chance encounters along the Rhine reveals itself upon closer inspection to be a deeply rooted, strategic tapestry that began generations earlier in Bad Berleburg. The Lehr family provided the initial social cement, after which the administrative structures of the foundation in Sankt Goar sealed the alliance.
This ironclad network of capital, intellect, and influence provided the solid social foundation for the subsequent international careers of the sons and grandsons of the Dülcken family within the flourishing world of European instrument making.

Archive Update: New Discoveries Regarding Johann Konrad Knöpfel in Marburg
Historical research never stands still. To reconstruct the intricate connections between the Dülcken and Knöpfel families and the Rhenish administration in even greater detail, we have initiated a comprehensive archival search at the Hessian State Archives in Marburg (HStAM). This search has proved highly successful, locating two crucial primary sources from 1701–1702 that shed direct light on Johann Konrad Knöpfel's exact official duties and sphere of influence:
HStAM, Bestand 40 a, Rubr. 04, Nr. 5143: The official “Instruktion für den Stiftskellner Johann Konrad Knöpfel zu St. Goar” (Instruction for the Estate Manager Johann Konrad Knöpfel at St. Goar, 1701–1702). This document will provide us with precise insights into his daily management of the church foundation's estates and finances.
HStAM, Bestand 40 a, Rubr. 04, Nr. 5144: The appointment decree “Bestellung des Proviantmeisters Johann Konrad Knöpfel zum Tranksteuererheber in der Niedergrafschaft Katzenelnbogen”(Appointment of Provisions Master Johann Konrad Knöpfel as Beverage Tax Collector in the Lower County of Katzenelnbogen, 1702). This serves as clear evidence of his immense economic and logistical power, being tasked with collecting the lucrative beverage tax right at the outbreak of the War of the Spanish Succession.
