Families covered: Gant (Gaunt) of Lincoln, Grentmesnil (Grandmesnil) of Grentmesnil, Geneville of Trim
 
Gilbert de Gaunt (Gant) (d c1095)
For some time we showed Gilbert as a son of Baldwin VI, Count of Flanders. This followed a well known view, supported by (inter alia) BE1883 (Gant of Lincoln), which describes Gilbert as "son of Baldwin, Earl of Flanders, by Maud, sister to William the Conqueror". Faith in that view is weakened by the fact that, as far as is known, William had no sister (or half-sister) Maud (although William was married to Baldwin VI's sister Matilda). We now follow the connection suggested by TCP (Lincoln) and supported by www.rootsweb.com/ ~medieval/gant.htm (which was kindly brought to our attention by a Visitor to this site).
m. Alice (dau of Hugh II de Montfort)
BE1883 reports that Gilbert had one wife, Alice de Montfort, but a Visitor to this site has reported that he had an earlier wife: Emma of Kyme. Alice was mother of Hugh and presumably therefore also of Hugh's younger brothers. It is possible, however, that Emma of Kyme was mother of one or both of Gilbert's daughters.

This family tree has been pulled together from data in various web sites but with some guidance from TCP (Leicester). The name Grandmesnil appears to have been an anglicised version of Grentmesnil, near Lisieux. The family appears to have been researched in some depth in recent years apparently because of interest in the fact that Hugh de Grentmesnil is reported to have been one of the close companions of William the Conqueror. This has led to the correction of previous confusion between his sons and the ancestry of Petronilla (Pernel) but the effects of that earlier confusion are not easy to unwind so the following should not be viewed as fully secure.
Gr31. Gervase de Grentmesnil (b c977)
Gr30 Robert de Grentmesnil
  m. Hawise (dau of Giroie d'Eschauffen)

  m2. Emma of Estuteville (dau of Robert de Estuteville)
  m3. Lucy (dau of Savary FitzCana)
  Some sources report that Robert dsp but TCP mentions one source that identifies one daughter, but by which wife is not certain:
  Gr27-1 Agnes de Grandmesnil
  m. Robert de Moulins
  TCP (Leicester) says of the Pernel (Petronilla) who married Robert de Beaumont that "we know that Pernel was great-grandaughter of Hugh the Domesday tenant" and speculates "if she inherited the Norman lands she would in all probability be a daughter of a son of Hugh's son Robert."

  Gr28-2 William de Grandmesnil
  m. Mabel of Apulia (dau of Robert 'Guiscard' de Hauteville, Duke of Apulia)
  Some sites suggest that William's elder brother Robert dspm and that William was father of the Pernel who married Robert de Beaumont. However, TCP says he went to Apulia "and no more is heard of him in England or Normandy."

Sir Geoffrey de Geneville, Sn de Vaucouleurs, Lord of Trim (b after 1225, d 21.10.1314)
BE1883 says that Geoffrey was son of Peter de Genevill who was either a man of humble birth or Lord of Vancouleur, brother of John de Joinville. We follow TCP which does not show such a Peter.
m. Maud de Lacy (dau of Gilbert de Lacy of Ewyas Lacy)
1. Geoffrey de Geneville (dvpsp before 11.10.1283)
2. Peter de Geneville of Ludlow (dvp before 08.06.1292)
  BE1883 suggests that Peter outlived his father and became 2nd Lord although it accepts that he was never summoned to Parliament.
