Maurice, Prince of Orange
However, Philip William, Prince of Orange William the Silent's eldest son, made an entailment that would override René's entailment, restoring the agnatic succession, and giving it to the male line of John VI, Count of Nassau-Dillenburg, William the Silent's brother. As it happened, the beneficiary of this provision was one William Hyacinth of Nassau-Siegen, who also vigorously contested the will in 1702. To complete the confusion, Maurice, Prince of Orange, Philip William's half-brother made an entailment that would give the succession to the male line of Ernst Casimir of Nassau-Dietz, a younger son of John VI, and the progenitor of John William Friso. This was (next to William's will) the main claim to the inheritance of John William Friso. (Frederick Henry's entailment overturned this entailment of his half-brother, if such a thing would have been possible; apparently he did not fancy the succession by Willem Frederik of Nassau-Dietz, who would otherwise have benefited).
