Answer the following question: Information:  - Wilfrid ( II ) or Wilfrith ( II ) ( died on 29 April in either 745 or 746 ) also known as Wilfrid the Younger , was the last Bishop of York , as the see was converted to an archbishopric during the time of his successor . In the 10th century , two different groups claim to have taken the relics of an earlier Wilfrid from Ripon ; most likely one party took those of Wilfrid the Younger . The younger Wilfrid 's feast is attested in the Calendar of Winchcombe and later martyrologies , though he does not seem to have had a widespread or popular veneration .  - England is a country that is part of the United Kingdom. It shares land borders with Scotland to the north and Wales to the west. The Irish Sea lies northwest of England and the Celtic Sea lies to the southwest. England is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain (which lies in the North Atlantic) in its centre and south; and includes over 100 smaller islands such as the Isles of Scilly, and the Isle of Wight.  - The Synod of Whitby (664 A.D.) was a Northumbrian synod where King Oswiu of Northumbria ruled that his kingdom would calculate Easter and observe the monastic tonsure according to the customs of Rome, rather than the customs practised by Irish monks at Iona and its satellite institutions. The synod was summoned at Hilda's double monastery of Streonshalh (Streanæshalch), later called Whitby Abbey.  - Wilfrid (originally spelled Wilfrith; c. 633  c. 709) was an English bishop and saint. Born a Northumbrian noble, he entered religious life as a teenager and studied at Lindisfarne, at Canterbury, in Gaul, and at Rome; he returned to Northumbria in about 660, and became the abbot of a newly founded monastery at Ripon. In 664 Wilfrid acted as spokesman for the Roman position at the Synod of Whitby, and became famous for his speech advocating that the Roman method for calculating the date of Easter should be adopted. His success prompted the king's son, Alhfrith, to appoint him Bishop of Northumbria. Wilfrid chose to be consecrated in Gaul because of the lack of what he considered to be validly consecrated bishops in England at that time. During Wilfrid's absence Alhfrith seems to have led an unsuccessful revolt against his father, Oswiu, leaving a question mark over Wilfrid's appointment as bishop. Before Wilfrid's return Oswiu had appointed Ceadda in his place, resulting in Wilfrid's retirement to Ripon for a few years following his arrival back in Northumbria.  - Ripon is a cathedral city in the Borough of Harrogate, North Yorkshire, England. Historically part of the West Riding of Yorkshire, it is located at the confluence of two tributaries of the River Ure, the Laver and Skell. The city is noted for its main feature, Ripon Cathedral which is architecturally significant, as well as the Ripon Racecourse and other features such as its market. The city itself is just over 1,300 years old.  - Gaul (Latin: "Gallia") was a region of Western Europe during the Iron Age that was inhabited by Celtic tribes, encompassing present day France, Luxembourg, Belgium, most of Switzerland, Northern Italy, as well as the parts of the Netherlands, Central Italy and Germany on the west bank of the Rhine. It covered an area of 190,800 mi² or 494,169 km². According to the testimony of Julius Caesar, Gaul was divided into three parts: Gallia Celtica, Belgica and Aquitania. Archaeologically, the Gauls were bearers of the La Tène culture, which extended across all of Gaul, as well as east to Raetia, Noricum, Pannonia and southwestern Germania during the 5th to 1st centuries BC. During the 2nd and 1st centuries BC, Gaul fell under Roman rule: Gallia Cisalpina was conquered in 203 BC and Gallia Narbonensis in 123 BC. Gaul was invaded after 120 BC by the Cimbri and the Teutons, who were in turn defeated by the Romans by 103 BC. Julius Caesar finally subdued the remaining parts of Gaul in his campaigns of 58 to 51 BC.  - The Holy Island of Lindisfarne is a tidal island off the northeast coast of England. It is also known just as Holy Island. It constitutes the civil parish of Holy Island in Northumberland. Holy Island has a recorded history from the 6th century AD. It was an important centre of Celtic Christianity under Saints Aidan of Lindisfarne, Cuthbert, Eadfrith of Lindisfarne and Eadberht of Lindisfarne. After the Viking invasions and the Norman conquest of England, a priory was reestablished. A small castle was built on the island in 1550.  - York is a historic walled city at the confluence of the rivers Ouse and Foss in North Yorkshire, England. The municipality is the traditional county town of Yorkshire to which it gives its name. The city has a rich heritage and has provided the backdrop to major political events in England throughout much of its two millennia of existence. The city offers a wealth of historic attractions, of which York Minster is the most prominent, and a variety of cultural and sporting activities making it a popular tourist destination for millions.    Given the paragraphs above, decide what entity has the relation 'date of death' with '800'.
