Notes:

Robert I de Ferrers, 1st Earl of Derby (c. 1068 – 1139) was born in Derbyshire, England, a younger son of Henry de Ferrières and his wife Bertha l'Aigle. His father, born in Ferrières, Normandy, France accompanied William the Conqueror during his invasion of England. The family was rewarded with a grant of Tutbury Castle in Staffordshire and 114 manors in Derbyshire.

Robert's elder brother William's main interests were in France. He joined Robert Curthose and was captured at Tinchebrai. His other brother Engenulf died shortly after his father and so Robert succeeded to the estates in 1088.

From the beginning, he gave great support to Henry I. As part of his tenure of Duffield Frith in 1129–30, he is on record as having interests in lead mines at Wirksworth. At about this time he granted the church of Potterspury, Northamptonshire, to Bernard the Scribe.

It is, however, during his last years that he is most in evidence as a leading supporter of King Stephen. He took a large body of Derbyshire men northwards to assist in repelling an invasion of the Scots under King David I of Scotland, nominally on the behalf of Matilda. Little actual fighting took place, but Thurstan, Archbishop of York, won the Battle of the Standard on Stephen's behalf, fought near Northallerton, on 22, August, 1138.

Robert was mainly instrumental in securing the victory for his Sovereign, who for this and other important services created him Earl of Derby, although charters and chronicles during this period refer to him interchangeably as Earl Ferrers, earl of Nottingham or earl of Derby.

He died in the following year (1139) and was succeeded in his earldom by his second but eldest surviving son Robert de Ferrers, 2nd Earl of Derby often known as Robert de Ferrars the Younger.

As with most Norman lords, the Ferrers brought their Norman underlords to England with them – in this case, the Curzon (of Kedleston), Livet (Levett) and Boscherville (Baskerville) families, who held their fiefs in Normandy from the Ferrers, and who subsequently held their English lands from Ferrers as well. (The undertenant family names derive from Notre-Dame-de-Courson, Livet-en-Ouche and Boscherville, all part of the Ferrers barony in Normandy.) These undertenant retained their ties to the Ferrers after the families had moved to England following the Norman Conquest.

Issue

Assuming Robert was born 1062 and Hawise was born 1086, assume they were not married earlier than her 16th birthday, or 1102. Brown suggests 1087 as the wedding date, which is too early if Hawises was born 1086. Children are shown born beginning in 1105, when she would have been 19, and continuing until she was 1118, when she would have been 32. These estimated birth years are realistic although unproved.

Notes:

Henry de Ferrers (died by 1100), magnate and administrator, was a Norman who after the 1066 Norman conquest was awarded extensive lands in England.
He was the eldest son of Walkeline de Ferrers and in about 1040 inherited his father's lands centered on the village of Ferrières-Saint-Hilaire.

In England he progressively acquired landholdings, which he had to manage. As one of the leading magnates, he also served King William I of England and his successor William II in administrative capacities and is said to have been castellan of Stafford Castle. In about 1080, he and his wife founded Tutbury Priory and in 1086 he was one of the royal commissioners in charge of the Domesday survey, which records his 210 manors.

He died between September 1093 and September 1100 and was buried in Tutbury Priory.

His first three tranches of land came to him from dispossessed English holders. First, in about 1066 or 1067, he was granted the lands of Goderic, the former sheriff of Berkshire, in Berkshire and Wiltshire. Then, by about the end of 1068, he obtained lands in Buckinghamshire, Essex and Northamptonshire, as well as more in Berkshire, that had belonged to Bondi the Staller. Finally, after the 1071 revolt, he was awarded the lands of Siward Barn in Derbyshire, Gloucestershire, Nottinghamshire and Warwickshire as well as further lands in Berkshire and Essex. Also after the revolt, he became holder of the Wapentake of Appletree centred on Tutbury Castle, which had been in the hands of Hugh d'Avranches and stretched across Derbyshire, Leicestershire and Staffordshire.
Among his under-tenants were members of families believed to have come from villages near his original home at Ferrières-Saint-Hilaire, such as the Curzons from Notre-Dame-de-Courson, the Baskervilles from Saint-Martin-de-Boscherville and the Levetts from Jonquerets-de-Livet.

Family
With his wife Bertha he had four known children:
1. William, probably the eldest, who inherited the estates in Normandy and was a supporter of Duke Robert Curthose.
2. Enguenulph, keeper of Duffield Castle, who did not long outlive his father.
3. Robert, who inherited the estates in England and was made Earl of Derby.
4. Amice, who married Nigel d'Aubigny, the probable brother of William d'Aubigny.

Notes:

André I st Vitre (born in 1054 and died circa 1135 ) is a baron Vitre about 1072 to his death, more than sixty years of reign.

«b»Biography «/b»
André I st dom Vitre is the eldest son of Robert I st and one of its two namesake wife Berthe Garin girl Craon or Berthe.

He succeeded his father around 1072 and married to 1091 Agnes, lady of Ryes in Normandy, daughter of Robert de Mortain. According to Pierre Le Baud, this marriage was concluded after a war between André I st to count of Mortain. In exchange for the release of the Norman count, Andre also receives six seigneuries in Cornwall, including the rich Triggshire. According to Louis Du Bois, the Baron de Vitré allegedly participated in a war with (or against) Alain Fergent, Duke of Brittanyin 1112, which would have pushed the sovereign to abdicate in favor of his son, Conan III. André I st recognizes without difficulty the authority of Duke Alain Fergent and his successor Conan III. In 1116 he handed over, in the presence of the latter, the Notre-Dame de Vitré church to the abbey of Saint-Melaine. In 1119 he attended Rennes with his son Robert at the funeral of Duke Alain Fergent.

According to Arthur of the Borderie "in 1132, Conan III was master of Vitre, and it exercised authority over natural lord of this land baron André I st. We do not know the reason for the conflict". It seems nevertheless that André became again baron soon after, since he died as a baron, in Vitré , in 1135. He is buried in the chapter of the church of Notre-Dame de Vitré. His son, Robert II, succeeded him but due, in turn, to be expelled from his stronghold by the Duke of Brittany from 1135.

«b»Union and posterity «/b»
From his marriage with Agnès de Mortain (also named Agnès de Morlaix), were born:

1.) Marquise

2.) Robert II of Vitré says the Old Man; also count of Mortain

3.) Gervais de Vitré, lord of Acigné, father of Militaries Guilaume de Vitré and Renaud de Vitré Dominus of Acigné. Author of the so-called "B kinship" of this family

4.) Elie

A certain Eudes (died in 1158 ) is sometimes considered as his son, but it would seem in fact that there is confusion with Eudes de Vitry, lord of Vitry and count of Rethel.

André married de Mortaigne, Agnes. Agnes (daughter of de Conteville, Earl Robert and de Montgomery, Countess Maud) was born in 1066 in Mortain, Manche, Basse-Normandie, France; died on 1 May 1121 in Mortagne, Orne, Basse-Normandie, France. [Group Sheet] [Family Chart]

He could also be lord of Marcillé, having received this fief of his uncle Robert de Marcillé, deceased without descendants. Marcillé -Robert\'s name could thus come from the name of the latter as well as from that of Baron de Vitré. «b»Biography «/b» Robert \"princeps and dom\" of Vitré, is the son of Baron Tristan de Vitré and his wife, Innoguen de Fougères. It was under his impulse that the first stone castle of the city was built, overlooking the Vilaine with its rocky outcrop. He founded, in fact, around 1070, the Sainte-Croix priory instead of the primitive castle of the first lords, as evidenced by certain charters. The Romanesque porch of the fortress of Robert Ier still exists today. Arthur de La Borderie notes that, in all likelihood, the beginnings of the city of Vitré and the foundation of the parish of Saint-Pierre (todayNotre-Dame ) date from the same period. Earlier, in 1066 , Robert fought under the orders of William the Conqueror, including participating in the Battle of Hastings on 14 October. «b»Union and posterity «/b» He marries around 1051 Berthe de Craon, daughter of Garin lord of Craon.

Notes:

Robert, Count of Mortain, 2nd Earl of Cornwall (c. 1031–c. 1095) was a Norman nobleman and the half-brother (on their mother's side) of King William the Conqueror. He was one of the very few proven companions of William the Conqueror at the Battle of Hastings and as recorded in the Domesday Book of 1086 was one of the greatest landholders in his half-brother's new Kingdom of England.

Life
Robert was the son of Herluin de Conteville and Herleva of Falaise and brother of Odo of Bayeux. Robert was born c. 1031 in Normandy, a half-brother of William the Conqueror. and was probably not more than a year or so younger than his brother Odo, born c. 1030. About 1035, Herluin, as Vicomte of Conteville, along with his wife Herleva and Robert, founded Grestain Abbey.

Count of Mortain
Around 1049 his brother Duke William made him Count of Mortain, in place of William Werlenc, who had been banished by Duke William; according to Orderic Vitalis, on a single word. William Werlenc was a grandson of Duke Richard I and therefore a cousin once removed to William, Duke of Normandy. Securing the southern border of Normandy was critical to Duke William and Robert was entrusted with this key county which guarded the borders of Brittany and Bellême.

Conquest of England
In early 1066, Robert was present at both the first council of Lillebonne, that of William's inner circle, and the second larger council held to discuss the Duke's planned conquest of England. Robert agreed to provide 120 ships to the invasion fleet, which was more than any other of William's magnates.

Robert was one of those few known to have been at the Battle of Hastings in 1066. He is pictured at a dinner at Pevensey on the Bayeux Tapestry, seated with his brothers William and Odo on the day of the landing in England. When granting the monastery of St Michael's Mount to the Norman monastery on the Mont Saint-Michel Robert recorded that he had fought at the Battle of Hastings under the banner of St Michel (habens in bello Sancti Michaelis vexillum).

Lands granted by William the Conqueror
Robert's contribution to the success of the invasion was clearly regarded as highly significant by the Conqueror, who awarded him a large share of the spoils; in total 797 manors at the time of Domesday. The greatest concentration of his honours lay in Cornwall where he held virtually all of that county and was considered by some the Earl of Cornwall.

While Robert held lands in twenty counties, the majority of his holdings in certain counties was as few as five manors. The overall worth of his estates was £2100. He administered most of his southwestern holdings from Launceston, Cornwall, and Montacute in Somerset. The holding of single greatest importance was the rape of Pevensey (east Sussex) which protected one of the more vulnerable parts of the south coast of England.

Later life
In 1069, together with Robert of Eu, he led an army against a force of Danes in Lindsey and effected great slaughter against them. After that there is little mention of Robert who appears to have been an absentee landholder spending the majority of his time in Normandy. Along with his brother Odo he participated in a revolt in 1088 against William II but afterwards he was pardoned. Robert died in 1095, possibly on 9 December, and chose to be buried at the Abbey of Grestain, near his father and next to his first wife Matilda.

Character
He was described by William of Malmesbury in his Gesta Regum as a man of stupid dull disposition (crassi et hebetis ingenii). William the Conqueror considered him one of his greatest supporters and trusted him with the important county of Mortain. Further clues to his character are found in the Vita of Vitalis of Savigny, a very wise monk who Robert sought out as his chaplain. One incident tells of Robert beating his wife and Vital, intervening, threatened to end the marriage if Robert did not repent. In still another entry Vital tells of his leaving Robert's service abruptly and after being escorted back to him, Robert begged for Vital's pardon for his actions. Overall, Robert was proficient in every duty William assigned him, he was a religious man yet ill-tempered enough to beat his wife, but was not known as a man of great wisdom.

Family
Robert was married to Matilda, daughter of Roger de Montgomery, 1st Earl of Shrewsbury, before 1066 and together they had:
1. William, Count of Mortain, who succeeded him.
2. Agnes who married André de Vitré, seigneur of Vitré.
3. Denise, married in 1078 to Guy, 3rd Sire de La Val.
4. Emma of Mortain, the wife of William IV of Toulouse.
Through Emma's daughter Philippa, Countess of Toulouse, Robert was the great-great-grandfather of Eleanor of Aquitaine and hence an ancestor of all English monarchs after Henry II.

After Matilda de Montgomery's death c. 1085 Robert secondly married Almodis. The couple had no children.
