Two Bigod sisters each married men named William d"Aubigny. Cecily Bigod married William "Brito" d'Aubigny while her sister Maud Bigod married William "Pincerna" d'Aubigny.

The d'Aubigny's of Belvoir are from this line, since Cecily inherited Belvoir from her mother, Adeliza de Toeni (Tosny/Toni).

Two brothers, one sister, parents not known:

1. ROGER Bigod (-1107, bur Thetford[905]). Domesday Book records “Roger Bigod” holding numerous properties in Norfolk and Suffolk[906]. "…Rogerus Bigotus…" subscribed a charter dated Sep 1101 under which Bishop Herbert donated property to Norwich priory[907]. "…Rogeri de Bigot…" subscribed a charter dated 14 Sep 1101 under which Henry I King of England donated property to Bath St Peter[908]. “Rogerus Bygot” founded Thetford Priory, with the advice of “…uxoris meæ Adeliciæ”, by undated charter dated to the reign of King Henry I[909]. The Annals of Bermondsey which record the death in 1107 of “Rogerus Bigod, principalis fundator monasterii Beatæ Mariæ Thetfordiæ”[910].

[m firstly ADELAIS, daughter of ---. The Liber Vitæ of Durham lists (in order) "Rodgerus Bigodus, Atheles uxor eius, Willelmus filius eorum"[911]. “Willielmus Bigot, dapifer regis Anglorum” donated property to Thetford Priory, for the souls of “patris mei Rogerii Bigoti et matris meæ Adelidis” and for the salvation of “fratris mei Hugonis et sororum mearum”, by undated charter dated to the reign of King Henry I[912]. The Complete Peerage[913] states that the wording of this charter shows that Adelais, mother of William, was deceased at the time, and must therefore have been a different person from Adelise de Tosny, Roger Bigod's [second] wife, who was recorded as alive in 1136. However, the question is open to debate as “pro anima” clauses are often difficult to interpret accurately.]

m [secondly] (before [1100]%29 ADELISE de Tosny, daughter of ROBERT de Tosny Lord of Belvoir & his wife Adelais --- (-after 1136[914]). Her parentage is indicated by the 1130 Pipe Roll which records "Adeliz uxor Rogi Big…tra patris sui de Belueder" in Lincolnshire[915], which also indicates that Adelise succeeded her sister Albreda in the Belvoir estates of their father. It is also indicated by the charter dated 23 Apr [1430] under which her descendant “Thomas dominus de Ros, de Hamelake, de Trussebout et de Beavoir” confirmed the possessions of Belvoir priory, Lincolnshire made by "antecessores nostros…Robertum de Toteneio, Willielmum de Toteneyo filium suum, Agnetem de Toteneio filiam dicti Roberti de Toteneyo, Henricum de Rya filium Huberto de Rya, Agnetem de Toteneyo, Willielmum de Albeneio primum, Willielmum de Albeneio secundum, Willielmum de Albeneio tertium, Willielmum de Albeneio quartum, Ywynum de Albeneyo, Heliam de Albeneyo et uxores eorundem, Isabellam filiam domini Willielmi de Albeneio quæ fuit uxor domini de Ros, domini de Beauvoire et de Hamelake"[916], the connection between Robert de Tosny Lord of Belvoir, father of Alice, being established through the marriage of her daughter Cecilia to William de Albini Brito.

The Complete Peerage states that he was William’s brother “presumably of the half-blood”, the basis for the statement being explained on the previous page[923]. He succeeded his [half-]brother as Lord of Framlingham. King Stephen created him Earl of Norfolk in [Dec 1140/Jan 1141]. - see below.

c) HUMPHREY Bigod (-after [1112/13]). Royal chaplain of King Henry I and prebendary of Totenhall 1101 to [1112/13][924].

It is not clear from this extract whether Gunnor’s father was named in the original document. Her first marriage is indicated by the charter of King Henry II which confirmed donations to Thetford Priory, including the donation by “Gunnoræ matris Henrici de Exessa”[927]. “Rob Waster” donated "duos partes totius decimæ meæ de Wereslai" to St Neot’s, Huntingdonshire, for the soul of “Soeni de Essessa” and for the health of "domini mei Roberti filii prædicti Soeni…Gunnor uxoris suæ…uxoris meæ et Willielmi filii Gerei patris sui", by undated charter[928]. “Hamo de Sancto Claro” donated “ecclesie Sancte Marie Walcre” to Colchester St. John, for the souls of King Henry I, Queen Matilda, “Eudonis dapiferi et...mee et uxoris mee Gunnoris et anime Huberti filii mei”, by undated charter (dated to before 1119), witnessed by “Willelmo de Sancto Claro, Huberto de Sancto Claro...”[929].

f) CECILY Bigod (-after 1136). Her parentage is indicated by the charter dated 23 Apr [1430] under which her descendant “Thomas dominus de Ros, de Hamelake, de Trussebout et de Beavoir” confirmed the possessions of Belvoir priory, Lincolnshire made by "antecessores nostros…Robertum de Toteneio, Willielmum de Toteneyo filium suum, Agnetem de Toteneio filiam dicti Roberti de Toteneyo, Henricum de Rya filium Huberto de Rya, Agnetem de Toteneyo, Willielmum de Albeneio primum, Willielmum de Albeneio secundum, Willielmum de Albeneio tertium, Willielmum de Albeneio quartum, Ywynum de Albeneyo, Heliam de Albeneyo et uxores eorundem, Isabellam filiam domini Willielmi de Albeneio quæ fuit uxor domini de Ros, domini de Beauvoire et de Hamelake"[935], the connection with Robert de Tosny Lord of Belvoir, her maternal grandfather, being established through her marriage.

Cecily Bigod

(circa 1086 - )

Cecily Bigod|b. c 1086|p69.htm#i14255|Roger Bigod|b. c 1060?\nd. 1106|p69.htm#i22632|Adeliza Todeni|d. 26 Nov 1120|p789.htm#i14261|Robert l. Bigod de Loges||p69.htm#i14307||||Robert d. Tosny|d. 1088|p789.htm#i14257|Adelais (?)||p1.htm#i14256|

    Cecily Bigod married William D'Aubigne (Brito I), son of Patriarch D'Aubigne.

She was of Belvoir. K S B Keats-Roahan wrote in Prosopon no. 9 (July 1998): In 1129 the sole surviving issue of Robert de Tosny were his younger daughters Adelisa Bigod and Agnes de Beaufour, who was then already married to Hubert de Ryes. At that date his Bigod granddaughter Matilda de Albini was probably already dead and her sister Gunnor not long removed from her second marriage to Haimo de St Clair. Of their siblings, only Hugh Bigod and Cecilia, then wife of William de Albini Brito, survived. The Carta returned by Hugh Bigod in 1166 shows him holding the fee of his aunt Albreda de Insula.[15] At the same date William de Albini Brito II held the fee of Belvoir. The conclusion from this must be that Adelisa succeeded Albreda in the fees of both Berengar and Robert de Tosny as next surviving sister. When she in her turn died she left issue of both sexes. Her sole surviving son Hugh succeeded his aunt Albreda - and by extension, her eldest brother Berengar - as heir both to Berengar's tenancy-in-chief in Lincolnshire and the Norman lands of Robert de Tosny of Belvoir. His tenancy of Robert's Norman lands is shown in a Norman record of 1172 where he is named as holding land of the fee of Conches and Tosny.[16] More important in terms of size in England, the lordship of Belvoir was nonetheless the lesser of the two Tosny lordships because it as not associated with their Norman heritage. As the inheritance of a woman married to an important tenant-in-chief it could be expected to pass to one of her younger children and not her husband's principal male heir. Since she had no surviving younger sons after 1120, the devolution of Belvoir to one of her daughters was inevitable. Gunnor and Matilda had long since been provided for from their father's inheritance by the time, after c. 1115/1118, that Adelisa succeeded to Belvoir. Consequently it was the youngest daughter Cecilia - quite probably a mere infant at her father's death in 1107 - who became her mother's heiress. She was, of course , an heiress whose marriage could advantageously be used to reward one of the king's loyal new men. Cecilia's marriage to William de Albini Brito has been said to have occurred as early as 1107 on the basis of a Belvoir charter given by Ralph de Raines and attested by Roger Bigod, but it certainly took place much later. The Belvoir charter just mentioned probably begins to the early 1140s . It was attested by William de Albini senior and his wife Cecilia, their son William junior, Roger Bigot, Robert de Toteneio, Ralph de Albeneio and others.[17] Since William, Robert and Ralph were certainly sons of William and Cecilia it is clear that Roger Bigod was also, as is confirmed by the order of their sons William, Robert, Roger, listed in the Thorney Liber vitae (BL Add, 40,000, fol. 2r). Cecily Bigod was born circa 1086. She was the daughter of Roger Bigod and Adeliza Todeni.
Children of Cecily Bigod and William D'Aubigne (Brito I)

* Ralph d'Aubigne d. before Michaelmas 1192
* William D'Aubigne+ d. bt 1166 - 1167

Cecily 'de Belvoir' (dau of Roger Bigod), m. William d'Aubignythe Breton, who had obtained part of the fee of Belvoir beforeCecily's mother was given possession of it; this marriage,therefore, may have been arranged to settle rival claims. Cecilyeventually inherited Belvoir from her mother (Hist. MSS. Com.,Rutland MSS., vol. iv. pp. 106-7, 144, 161) [Ref: Utz 10 Jan1999 citing: Geoffrey H. White essay on 'Norfolk' in CPIX:578(c)]

I. J. Sanders, English Baronies, in his discussion of Belvoir,Leicestershire, p. 12, says: 'Robert de Todeni, Domesday lord ofBelvoir, d. 1088. William, s. and h., d.s.p. when his heir forBelvoir was his sister Alice.

'Alice m. Roger Bigod d. 1107 of Framlingham, q.v. She d. postAug. 1127 leaving Cecily.

'Cecily m. William I de Albini Brito d. 1133-55.[3] William IId'Aubigny d. 1168 leaving William III, a minor, d. 1236. . . .'

Footnote 3 reads: 'Regesta, ii, no. 1495; Rutland MSS, iv, pp.144, 161. William seems to have controlled part of the Belvoirestate before the death of Alice (idem, p. 107). Williamwitnesses letters dated 1133 but the early pipe rolls of HenryII give no evidence of his death (Regesta, ii, nos. 1777,1798).'

[Sanders' phrase, 'leaving Cecily,' clearly implies, from hisusage throughout '. . . as daughter and heir.']

Anthony Wagner, English Genealogy, p. 66, comments: '. . .William d'Aubigny the Breton did indeed succeed a son of Robertde Tony at Belvoir, but it was, as Round showed, in virtue ofhis marriage to Robert's granddaughter Cicely.[3]' Footnote 3reads: 'Hist. MSS. Comm. MSS. of the Duke of Rutland, iv. 106;Complete Peerage, ix, 577. [Ref: Utz 10 Jan 1999 (Alan B. Wilson14 Dec 1997)]

More important in terms of size in England, the lordship ofBelvoir was nonetheless the lesser of the two Tosny lordshipsbecause it was not associated with their Norman heritage. As theinheritance of a woman married to an important tenant-in-chiefit could be expected to pass to one of her younger children andnot her husband's principal male heir.
