Mother: Adeliza de Toni, b. ca. 1060 in St. Saveur, Normandy, France, d. aft. 1135
During the English civil war, Hugh switched sides from Empress Matilda to Stephen and back again several times. It is supposedly from Hugh that we get the words "bigot" and bigotry".

We have found no other sources supporting more than three of the children listed here: Roger, Hugh, and William Hugh. The others are probably incorrectly ascribed to Hugh.

Roger Bigod, Sheriff of Norfolk, b. ca. 1045, m. Adeline de Grentmesnil, ca. 1093, d. 9 September 1107

Father: Robert (Roger) le Bigot, b. ca. 1025 in St. Saveur, Normandy, France
Roger, along with Robert Malet and Ralph de Gael (then Earl of Norfolk), in 1069 defeated Sweyn II of Denmark (Sveyn Estridsen) near Ipswitch. After the fall of Ralph de Gael in 1074, Roger was appointed Sheriff of Norfolk and Suffolk. He also aquired many of the former Earl's estates. He is sometimes called the first Earl of Norfolk, but he was never created earl.

There was a dispute between the Bishop of Norwich, Herbet Losinga, and the monks at Thetford over where Roger was to buried. The monks claimed that Roger, as well as his family and successors, should be buried at the Priory Roger founded at Thetford as part of the foundation charter. The issue was settled when the Bishop stole Roger's body and took it to Norwich.

We have found no confirmation of Roger's marriage to Adeline de Grentmesnil. Most historians now believe the several Adelaides, Adelizas, Alices, and Adelines Roger was supposed to have married were actually all Adeliza de Toni (or Toeni, Toeny, Tosny).

Spouse: Adeliza de Toni, b. ca. 1060 in St. Saveur, Normandy, France, d. aft. 1135

Father: Robert de Toni, b. ca. 1030 in Belvoir, Leicestershire, England, d. August 1088

Married ca. 1080 in Leicestershire, England.

  1. Gunnor Bigod, b. ca. 1087, m. Robert, Lord of Rayleigh
  2. Cecily Bigod, b. ca. 1090 in Belvoir Castle, Belvoir, Leicestershire, England, m. William "Brito" d'Aubigny, Lord of Belvoir, d. 5 December 1135 in Belvoir, Leicestershire, England
  3. Maud Bigod, b. ca. 1093, m. William d'Albini "Pincerna", Lord of Old Buckenham Castle
  4. William Bigod (3), b. ca. 1094, d. 26 November 1119, cause of death was drowning in the sinking of the White Ship.
  5. Hugh Bigod, 1st Earl of Norfolk, b. 1095 in Belvoir Castle, Leicestershire, England, m. Julianne de Vere, ca. 1149 in England, m. Gundreda Warwick, ca. 1165 in Warwick, Warwickshire, England, d. 1177 in England

Robert (Roger) le Bigot, b. ca. 1025 in St. Saveur, Normandy, France

Robert gained great favor in the court of William the Conqueror, supposedly by warning him of a plot by William's cousin, William of Mortain.

That Robert le Bigot is the father of Roger Bigod is considered speculative.

Children:

  1. Roger Bigod, Sheriff of Norfolk, b. ca. 1045, m. Adeliza de Toni, ca. 1080 in Leicestershire, England, m. Adeline de Grentmesnil, ca. 1093, d. 9 September 1107
