Pernel (Petronille) DE GRENTMESNIL
- Born: Leicestershire, England
- Married: Before 1155/9
- Died: 1 Apr 1212, Leicester, Leicestershire, England
- Buried: Abbey, Leicester, Leicestershire, England
Pernel is named as great-granddaughter of Hugues de Grantmesnil in the [1190/1204] charter of her son Robert FitzPernel to the abbey of St Evrou. Her father is named Hugh de Grantmesnil in an account of the foundation of Leicester Abbey, but the Complete Peerage casts doubt on the accuracy of this... Robert de Torigny records that her husband gained the Norman honour of Grantmesnil through his marriage, which suggests that Pernel, as heiress, was descended from the oldest son of Hugues de Grantmesnil senior. It is possible that she was the daughter of Agnes, daughter of Robert de Grantmesnil. Considering that Orderic Vitalis does not name Hugues (supposed brother of Agnes) although he is so thorough in naming other members of this family, this is the most likely possibility.
"Robertus filius comitis Legrece" donated property to Notre-Dame de la Trappe for the soul of "uxoris mee Petronille" by charter dated [1153/67]. "Petronilla comitissa Leircestrie" confirmed the exchange of land with Nuneaton priory made by "Robertus comes Leircestrie filius meus", who gave land in Belgrave in return for land in Dadlington which had been donated by "sponsus meus Robertus comesůcum filia mea pie memorie Hawis", by charter dated to after 1189. The Testa de Nevill lists knights who held land from the king in Hertfordshire, dated to [1204/12]: "comitissa de Leicestria" held "Wares".
The necrology of Lyre monastery records the death "1 Apr" of "Petronilla comitissa LeicestriŠ". The necrology of the monastery of Ouche records the death "1 Apr" of "Petronilla comitissa LeycestriŠ".
Pernel married Robert "ès Blanchemains" DE BEAUMONT, 3rd Earl of Leicester, son of Robert II DE BEAUMONT-LE-ROGER, 2nd Earl of Leicester and Amicie DE GA╦L, Countess of Leicester, Heiress of Breteuil. (Robert "ès Blanchemains" DE BEAUMONT was born in Leicester Castle, Leicestershire, England and died on 31 Aug 1190 in Durazzo Provence, West Albania.)
