In late 1206 or early 1207, Hugh was married to Maud Marshal (1192 - 27 March 1248), daughter of Sir William Marshal, 1st Earl of Pembroke and Isabel de Clare, 4th Countess of Pembroke. Together they had the following children:
Contrary to the assertion of Frederick Lewis Weis, Ancestral Roots, there is no evidence for a fourth son called Simon Bigod. A man of that name appears as a witness to one of Earl Hugh's charters [Morris, HBII 2], but as the eighteenth name in a list of twenty, suggesting no close connection to the main branch of the family. He is also named among the knights who surrendered to King John at Framlingham Castle in 1216. He was a probably a descendant of Hugh or William Bigod, half-brothers to Earl Roger II Bigod.
Very soon after Hugh's death, Maud married William de Warenne, 6th Earl of Surrey
