Wer heiratete Wilhelm IV. (Ponthieu)?

Wilhelm IV. Talvas, je nach Zählweise auch Wilhelm II. Talvas (* 1179; † 4. Oktober 1221) aus dem Haus Montgommery war Graf von Ponthieu und damit ein Vasall des Herzogs der Normandie. Er war der Sohn und Erbe von Graf Johann I. († 1191) und Beatrix von Saint-Pol.

Alys of France, Countess of Vexin (4 October 1160 – c. 1218–1220), known in English as "Alice", was a French princess, initially betrothed to Richard I of England. Her engagement was broken in 1190, through negotiations between Richard and her half-brother Philip Augustus of France. Philip then attempted to betroth her to Richard's brother John but this betrothal was rejected. Alys married William IV, Count of Ponthieu, on 20 August 1195. She died between 1218 and 1220.
