G.W. Miller 1991, "Reconstructing the Op Den Graff windows of 1630 A.D. to fit the Lohengrin Genealogy of the House of Cleves, "Krefeld Immigrants and Their Descendants, vol. 8, #1, pp. 9-28. Graeffvon Alten (Count of Altena)

1592, became Protestant Bishop of Muenster and the last Duke (Herzog) of Cleves of the House of La Marck (a branch of the House of Boulogne, itself a branch of the Lohengrin family which allegedly can be traced back to the fifth century) upon the death of his father.
1599, married Antonia of Lorraine.
1609, died without an heir to his feudal title. No non-royal children mentioned, but it is argued that they would have been given the patronymic "op den Graff" (of the Count), "zu Graff" (belonging to the Count), van de Graff (of the Count), "de Graff" (of Count) while he was Graff or Count, or later when he has been elevated to Duke or Herzog," op den Herzog" or "de Hartog".
At this time the multiple dukedom of Cleves-Julich-Berg was divided and invaded by armies from the Houses of Brandenburg, Zweibrucken and Wittelsbach, all relatives of the House of Cleves. Their 9 year family dispute was followed by the Thirty Years War driven by religious differences.
Johann Wilhelm first married Anna van Aldekerk. Born in 1565 in Aldekerk, Muir, Germany. Anna died in Aldekerk, Muir, Germany.
They had one child: Herman (1585-1642)
In 1585 when Johann Wilhelm was 22, he second married Jacobea of Baden, 13. Born in 1558. Jacobea died in Dusseldorf, Germany, in Sep 1597; she was 39.
