Charles Martel went on to become Duke of all the Franks and founder of Carolinian line of Kings. Thirteen years later in 732 he defeated the Saracen Army at Poitiers in France, and saved Western Europe from complete invasion by the Moslems. As a result of this, his son Pepin III, became 1st King of the Franks. Pepin in turn was the father of Charlemagne and Berta. Charlemagne, 2nd King of the Franks, is the ancestor of every existing and former ruling house or dynasty in Europe. His sister Berta was joined in marriage to Milo de Ver, the son of Rainfroi de Ver, in 800 AD, the same year her brother was crowned Holy Roman Emperor.
The name "Ver" probably comes from the latin "verus", which means "true". It may have been used as a title for the counts of Anjou. Another possible explanations is that it originated from the name of an ancestral village in Normandy, near Bayeaux and the River Vire. The name of the town itself came from the Norse word for "station", and referred to Viking staging points.
Milo de Ver was the Duke of Anjou, Count of Angleria, and Duke Leader of Charlemagne's house. Milo and Berta had two sons, one being Roland (legendary Paladin for whom "Song of Roland" was written) and Milo de Ver II. The de Ver line passed from Milo II through a succesion of Earls of Genney: Milo II 's son Nicasius de Ver was father to Otho de Ver, father to Amelius de Ver, father to Gallus de Ver, father to Mansses de Ver, father to Alphonsus de Vere. Alphonsus, Earl of Genney, was "Councilor to Edward the Confessor" King Edward III of England, who had both Norman and Flemish advisors. Alphonsus de Vere had a son Alberic, also known as Aubrey I. (Aubrey comes from the Teutonic name Alberic, or "elf-ruler.")
The first Aubrey de Vere on record (in Britain) came to England with William the Conqueror. He is usually held to be a Norman, though he may have been a Breton; he certainly had strong Connections with Brittany. Before the Conquest he was described as one of the barons of Conan, Count of Brittany, and after the Battle of Hastings he or his son (a second Aubrey) was allotted lands in Essex by the overlord there, who was Alan of Brittany, now called Alan, Count of Richmond in Yorkshire.
Alberic de Vere was the eldest surviving son of Alberic de Vere who had followed William the Conqueror to England in or after 1066. Their lineage is probably Norman, possibly originally from the eponymous town of Ver/Vire in western Normandy, and were said to descend from Charlemagne himself through the counts of Flanders by late antiquarians. King Henry I declared the first Lord Great Chamberlain Robert Malet's estates and titles forfeit, and in 1133 awarded the office of Lord Great Chamberlain to Aubrey, whose son Aubrey de Vere III, was created Earl of Oxford, and whose descendants were to hold the title until 1703.
Aubrey de Vere III was created Earl of Oxford by the empress Matilda in July 1141. He inherited the barony of Hedingham on the death of his father Aubrey de Vere II in May 1141, when he was already Count of Guines by right of his wife Beatrice. He lost the latter title on the annulment of their marriage 1144-46. Earl Aubrey was little involved in national political affairs after this period. His attempt to divorce his third wife, Agnes of Essex, was a celebrated marriage case that Agnes appealed successfully to Pope Alexander III.
Robert (de Vere), 3rd Earl of Oxford was 8th in descent from Hugh Capet, King of Franks. He was baptized in 1164. He married Isabel de Bolbec, daughter of Hugh II, 2nd Baron de Bolbec, before 1210. He may have been the "Robin Hood" of legend. He was heir to his brother, Alberic IV, to the earldom of Oxford circa 1215. He was a Magna Carta Surety. He died on 25 October 1221 at age 57 years. Robert (de Vere), 3rd Earl of Oxford was buried in the Priory of Hatfield, Broad Oak, Essex, England.
