Countess Wilhelmine Christine of Nassau-Siegen (1629 – 22 January 1700), German: Wilhelmine Christine Gräfin von Nassau-Siegen, official titles: Gräfin zu Nassau, Katzenelnbogen, Vianden und Diez, Frau zu Beilstein, was a countess from the House of Nassau-Siegen, a cadet branch of the Ottonian Line of the House of Nassau, and through marriage Countess of Waldeck-Wildungen [nl].
Count William Frederick of Nassau-Diez, the stadtholder of Friesland, noted in June 1645 in his diary that the sixteen-year-old Wilhelmine Christine was the favourite girlfriend of PrinceWilliam II of Orange, "die hij zoo dicwils custe als hij woude, alleen sijnde, en de borstjes tastede" ("whom he kissed as much as he wished, being alone, and touching the breasts"). William II had to promise Wilhelmine Christine "sich deechlijck te hauden" ("to stay decent"), but the consequence of this intimacy was that her mother Christiane did not want Wilhelmine Christine to be alone with Prince William, "doch dat sie het allebeide sochten" ("but that they both sought it").[9] When Christiane came in "maeckte prins Wilhelm den slaepert" ("Prince William sneaked out").[10]
Also after the death of Christiane in 1646, the prince was still in contact with Wilhelmine Christine. In November 1648, William Frederick wrote in his diary that William had told him that he had secretly visited her dozens of times and had seen her in bed twice, but that he had stayed "degelijck" ("decent"), "niet als kussen en eens geraeckt, doch en passant en op het lest" ("nothing but kissing and touching, but in passing and at the last moment"). Earlier, William had mentioned that he would have wanted Wilhelmine Christine "heel" ("complete"); he would have preferred her as wife to anyone else.[11]
Wilhelmine Christine outlived her husband by almost 31 years; she died in Hildburghausen on 22 January 1700[1][note 5] and was buried in Saalfeld on 27 January.[2]
^"She was certainly not born in 1625, as Europäische Stammtafeln claims. She was baptised in Heusden on 10-6-1629 and probably born there. However, it should be noted that William of Nassau-Siegen notified the birth of his daughter on 31-5-1629 from Ortheim (See: State Archives Wiesbaden 170III)."[2]
^"Dek (1970): married in Helsen, suburb of Arolsen 26-1-1660. This is a misinterpretation of the marriage certificate. One does indeed find in the Helsen parish records, the marriage certificate, but in this one it says: «1660 den 26 Januar ist der Hochgeborene Graff und Herr, Herr Josias Graff zu Waldeck u. Piermont … mit der Hochgebohrenen Gräfinnen Frewlein Wilhelmine Christina, Frewlein von Nassau, Catzenelnbogen, Vianden u. Diez, uff Arolsen abends umb 7 Uhren copulirt worden». One finds the date 26‑1‑1659 in Europäische Stammtafeln I, 117."[12]
^Dek (1970), p. 88, Dek (1968), pp. 276 and 297, Hoffmeister (1883), p. 63 and Vorsterman van Oyen (1882), p. 117 mention the date 31 July 1636 without specification of the calendar they used.
^von Poten (1896), p. 677 mentions the date 29 July. Dek (1970), p. 88, Dek (1968), pp. 276 and 297, Hoffmeister (1883), p. 63 and Vorsterman van Oyen (1882), p. 117 mention the date 8 August. Presumably, the former author calculated the date according to the Julian calendar and the latter authors according to the Gregorian calendar.
^"Died on 21-1-1700 according to Europäische Stammtafeln I, 117; on 22-1-1707 according to Europäische Stammtafeln I, 139 and Hoffmeister (1883), confirmed by Dek (1970), with Saalfeld as place of death. But the death does not occur in the parish registers of Saalfeld, neither in January 1700 nor in January 1707. Saalfeld must be excluded as a possible place of death. Waldeckischer Helden – und Regenten – Saal, a manuscript written in 1737 by the Geheimrat August von Klettenburg and preserved in the State Archives Marburg, mentions that the Fürstin died at Cuylenborg in Holland on 21-1-1700. It is possible that she was mistaken for her sister-in-law Juliane Elisabeth, who was called «Gräfin Cülenborg» and died in 1707, which seems to be a cause of the mistake for some authors who, as we have seen, have the Fürstin die in that year. Finally, in the book Bau und Kunstdenkmäler, Kreis der Eder is claimed that she died in Altwillungen Castle. None of these claims are true. The death certificate can be found in the parish registry of Hildburghausen, Stadtkirche, part I, p. 475 R, year 1700: «Die Hochgeb. Gräfin u. Frau Wilhelmine Christina Verwittibte Gräfin zu Waldeck Wildungen, gebohrene Gräfin zu Nassau usw. wird aus diesem Hochfürstl. Residence Schlosse, den 22. January seelig Entschlafen, den 27, abendts umb 7 Uhr in Hochansehentlichen Leichenprocess von hier auf bis vors thor Begleithet, und so ferner auf Saaltfeld gebracht worden.»"[2]
