Johann married Maria Magdalena Keverich in 1767; she was the daughter of Heinrich Keverich (1701–1751), who was head chef at the court of Johann IX Philipp von Walderdorff, Archbishop of Trier. Beethoven was born of this marriage in Bonn, at what is now the Beethoven House Museum, Bonngasse 20. There is no authentic record of the date of his birth; but the registry of his baptism, in the Catholic Parish of St. Remigius on 17 December 1770, survives, and the custom in the region at the time was to carry out baptism within 24 hours of birth. There is a consensus (with which Beethoven himself agreed) that his birth date was 16 December, but no documentary proof of this.
