After about 500 AD, England comprised seven Anglo-Saxon territories – Northumbria, Mercia, East Anglia, Essex, Kent, Sussex and Wessex – often referred to as the heptarchy. The boundaries of some of these, which later unified as the Kingdom of England, roughly coincide with those of modern regions. During Oliver Cromwell's Protectorate in the 1650s, the rule of the Major-Generals created 10 regions in England and Wales of similar size to the modern region

The Heptarchy (from the Greek ἑπτά hepta, "seven" and ἄρχω arkho, "to rule") is a collective name applied to the Anglo-Saxon kingdoms of south, east and central England during late antiquity and the early Middle Ages, conventionally identified as seven: East Anglia, Essex, Kent, Mercia, Northumbria, Sussex and Wessex. The Anglo-Saxon kingdoms eventually unified into the Kingdom of England.

The Kingdom of Lindsey or Linnuis (Old English: Lindesege) was a lesser Anglo-Saxon kingdom, which was absorbed into Northumbria in the 7th century.
Lindsey lay between the Humber estuary and the Wash, forming its inland boundaries from the courses of the Witham and Trent rivers, and the Foss Dyke between them. A marshy region south of the Humber known as the Isle of Axholme was also included.
All trace of Lindsey's separate status had vanished before the Viking assault in the late ninth century. Its territories were absorbed into the historical English county of Lincolnshire, the northern part of which is called Lindsey.

Hwicce was a tribal kingdom in Anglo-Saxon England. According to the Anglo-Saxon Chronicle, the kingdom was established in 577, after the Battle of Deorham. After 628, the kingdom became a client or sub-kingdom of Mercia as a result of the Battle of Cirencester.
The Tribal Hidage assessed Hwicce at 7000 hides, which would give it a similar sized economy to the kingdoms of Essex and Sussex.
The exact boundaries of the kingdom remain uncertain, though it is likely that they coincided with those of the old Diocese of Worcester, founded in 679–80, the early bishops of which bore the title Episcopus Hwicciorum. The kingdom would therefore have included Worcestershire except the northwestern tip, Gloucestershire except the Forest of Dean, the southwestern half of Warwickshire, the neighbourhood of Bath north of the Avon, plus small parts of Herefordshire, Shropshire, Staffordshire and north-west Wiltshire.
... The territory of the Hwicce may roughly have corresponded to the Roman civitas of the Dobunni.

The Middle Angles were an important ethnic or cultural group within the larger kingdom of Mercia in England in the Anglo-Saxon period.
It is likely that Angles broke into the Midlands from East Anglia and the Wash early in the 6th century. Those who established their control first came to be called Middil Engli (Middle Angles). Their territory was centred in modern Leicestershire and East Staffordshire, but probably extended as far as the Cambridgeshire uplands and the Chilterns. This gave them a strategically important place within both Mercia and England as a whole, dominating both the great land routes of Watling Street and Fosse Way, and the major river route of the River Trent, together with its tributaries, the Tame and Soar.
The Middle Angles were incorporated into the wider kingdom of Mercia, apparently well before the reign of Penda (c.626-655)

всю территорию Уэльса можно разделить на независимый Уэльс (Pura Wallia) и приграничный Уэльс (Welsh Marches, Marchia Wallie - lands ruled by the Marcher barons), неточно определенная область вдоль и вокруг границы между Англией и Уэльсом

Hundreds of small castles were built in the border area in the 12th and 13th centuries, predominantly by Norman lords
The Marcher lords encouraged immigration from all the Norman-Angevin realms
Peasants came to Wales in large numbers: Henry I encouraged Bretons, Flemings, Normans, and English settlers to move into the south of Wales
The Norman lords each had similar rights to the Welsh princes

независимое положение Earldom of Chester (county palatinate) и культурной близостью к Уэльсу объясняется тем, что до 602 года эта область входила в состав владений Gwynedd

In a rare show of common interest it appears Gwynedd and neighbouring Powys acted in concert to rebuff the Anglican advance but were defeated at the Battle of Chester in 613. Following this catastrophe the approximate borders of northern Wales were set with the city of Caerlleon (now called Chester) and the surrounding Cheshire Plain falling under the control of the Anglo-Saxons
In early times Gwynedd (or Venedotia) may have been ruled from Chester. After the Battle of Chester in 613 when the city fell to the Anglo-Saxons

The native inhabitants of medieval Wales were descended from the Celtic Britons, whom the Anglo-Saxons had driven out of the island's fertile midlands (the term "Welsh" was the Anglo-Saxon word for "foreigner"). In the 8th century the Anglo-Saxons established the traditional Anglo-Welsh border by erecting King Offa's Dyke, an earthwork barrier running from the coast near to Prestatyn in the north to the Bristol Channel in the south. While Offa's Dyke marked the end of Anglo-Saxon annexation of Welsh territory, the status quo was shattered in the 11th century by the arrival of the Normans, who conquered a border zone in Wales known as the Marches (from a French word meaning "frontier"). Norman warlords known as Marcher lords oversaw the conquered lands and prevented incursions by outsiders. Over time, a hybrid society developed in this frontier area as Welsh, Anglo-Saxon and Norman peoples and cultures mixed together. Until Edward's invasion in 1277, the country remained divided between Marcher Wales and native Wales.

это объясняется пограничным расположением этой деревни
(Link)
It is located on the banks of the River Dee, south of Chester, and close to the border with Wales
Up to the 14th century, Farndon also included the chapelry of Holt in Denbighshire, Wales
Farndon is very close to the border between England and Wales (the actual border is on the bridge which crosses the river Dee and which separates Farndon and the village of Holt.) Consequently, Farndon has a Welsh name: Rhedynfre. The village was an important place historically and has been a site of conflict and cultural exchange since the Angles settled the area in the 8th century. The border moved numerous times during the following centuries, placing Farndon alternately in Wales and England.

поэтому этот памятник можно отнести к региону Уэльс

Датировка памятников Ирландии большей частью предположительная, выведенная из аналогии (композиция фигуры, изображенный костюм, детали) с английскими и больше с континентальными памятниками - север Европы и Галисия.
Доказательства того, что указанная на памятниках более поздняя датировка была нанесена при использовании старых скульптурных надгробий при строительстве новых памятников:
- надписи часто не умещаются и нанесены кусками
- в надписи указано, что художник (которому современные источники приписывают изготовление памятников) оставлял подпись "SCRIPSIT" ("написал", а не изваял-создал)
- на некоторых памятниках видно, что плита с фигурой отдельна от общего памятника и надписи (см. P0614b-камни с надписью обкладывают отдельную плиту с фигурой)
