William VI (c. 1173 - 17 September 1226) was the Marquess of Montferrat from 1203 and pretender to the Kingdom of Thessalonica from 1207.
Boniface I's eldest son, and his only son by his first wife, Helena del Bosco, William stood originally to inherit all his father's possessions. He participated in diverse campaigns with his father, including the Battle of Montiglio, in which the men of Asti were defeated in 1191. Between 1193 and 1199, he appeared in many of his father's public acts. On 12 June 1199, he was put in charge of Acqui Terme with twenty knights to combat the Alessandrini, and, on 27 October, he was present near Saluggia for the signing of a pact with the commune of Vercelli.
On 9 August 1202 William married Berta (1182-1224), daughter of the Marquess Bonifacio di Clavesana, Count of Cortemiglia. They had at least three children:
Boniface II, Marquess of Montferrat (born ca 1203, date of death unknown).
Beatrice (ca 1210-1274), Lady of Saint-Bonnet in her own right. She married three times:
On 15 November 1219, Guigues VI of Viennois
In 1252, Guy II, Lord of Bauge
Pierre de la Roue
Alix (ca. 1215-1232), married in May 1229 Henry I of Lusignan, King of Cyprus.
Oddone di Monferrato (died 1251), who became Bishop of Porto, and Cardinal in 1227, may have been a son of William VI; whether he was legitimate or not is uncertain.
