Zeger III of Ghent

Zeger III of Ghent (called The Good) was the lord of Heusden, of Bornhem, and of Saint-Jean Steen, and the Châtelain of Ghent. He was the second son of Zeger II, Lord of Ghent and Petronella of Coutrai. His older brother, Arnold, died before 1190, leaving him the heir to the estate of his parents. He took his title of lord of Ghent, Bornhem, and Saint-Jean Steen around 1199. He married Beatrix of Heusden, and through her became Lord of Heusden, a title which was held by his son and progeny.

Beatrix was the daughter of Hughes of Heusden, son of Anselm III, Lord of Heusden (not to be confused with his cousin, Hughes of Heusden, son of Anselm's brother Eustace, Lord of Choques).
