He was the son of Henri de Thourout, knight, who is mentioned in an act of 26 February 1279, and who probably died before 21 August 1281.
He also held land in Menen and Rekkem, a manor in Varsenare, and owned a number of houses within the city of Ypres.
[1] Most of his land fell under French occupation, and without that revenue he was obliged to raise loans within the city secured by his property there.
The French declared his lands elsewhere forfeit, awarding his manor in Varsenare to Dominique Maere in April 1299, and his lands in Menen, Rekkem and Wervik to Raoul de Clermont later the same year.
The last documentary trace of his life records that in December 1301 he was imprisoned at Loudun.
