Another example of the broad meaning of the word "neptis" in this period is its use for King Henry I's kinswoman, Sibyl of Falaise, in the Curia Regis Rolls. As best I know, King Henry had no niece named Sibyl of Falaise. The assertion by one author that the word "neptis" might be an euphemism for an illegitimate daughter seems unfounded. Rather, Sibyl of Falaise was simply a near kinswoman of undeterminate relationship to King Henry I of England. [Ref: Douglas Richardson 24 Feb 2002]
Henry I gave the honour of Montgomery (in Wales) to Baldwin de Boulers on his marriage to Sibyl de Falaise. Sibyl was some kind of relation, probably cousin, of Henry I, but not niece as is interpreted from the latin...
The IPM of Vitalis Engayne in 1248 (CIPM 1: 166) says for Suffolk "Badmundefeld, a moiety of the manor (extent given) held of the honour on Mungumeri without service, because King Henry, the king's great-great grandfather, gave the manor in free marriage to Baldwin de Bulers, ancestor of the said Vitalis, with Sibyl de Falaise his niece."
The division is reiterated in the IPM of William de Cantilupo in 1253 (CIPM 1 : 318) Suffolk. "Badmundefield manor (extent given). King Henry I gave the manor to Baldwin de Boulers in free marriage with Sibyl de Faleisse, wherefore no service has ever been done to the king for the same. " [Ref: Rosie Bevan 8 May 2002]
father: William de Falaise [Ref: CP V:72chart]
parents: Domesday People, p.474 has Sybil as daughter of William de Falaise possibly son of William de Moulins, son of Walter de Falaise, brother of Herleve de Falaise, mother of Duke William. Sybil's mother was Geva, da. and heiress of Serlo de Burcy, Lord of Blagdon, Somerset. Geva was previously married to Martin and her son and heir was Robert fitz Martin d.1159. See also Sanders p.15, 22, 23. [Ref: Rosie Bevan 9 May 2002] caveat emptor: Sibyl's connection to Herleve, mother of Wm. the C., is (though certainly possible) speculation which, at this time lacks documentary proof... Curt
parents: Keats-Rohan in Domesday Descendants has Sibilla de Falesia as younger daughter of William de Falaise and Geva de Burcy. "She was given in marriage to Baldwin de Boullers by Henry I, who described her as his 'nepta', i.e. kinswoman". Sources: Johnson/Cronne, RRAN II, App. no. cccix; Tremlett and Blakiston, Stogursey Charters (1949(, no 1) [Ref: Renia Simmonds 9 May 2002]
caveat emptor: there are numerous pedigrees online that erroneously make Sibyl the illeg. dau. of Henry I... Curt
